The Most Dangerous Game, written by Richard Connell, is a thrilling short story about a hunter named Sanger Rainsford who becomes the prey in a twisted hunting game organized by a wealthy Russian aristocrat named General Zaroff.
The story begins with Rainsford and his friend, Whitney, discussing their differing beliefs about the value of hunting. Rainsford, an experienced hunter, believes that hunting is the ultimate sport because it requires skill and strategy, while Whitney sees it as a barbaric and unnecessary activity.
As the story progresses, Rainsford finds himself stranded on an island after falling overboard from his yacht. He is eventually discovered by General Zaroff, who invites him to stay at his mansion on the island. However, Rainsford soon learns that Zaroff has a twisted hobby: he hunts humans as the ultimate prey.
Zaroff tells Rainsford that he has grown bored of hunting animals and has turned to hunting humans because they provide a more challenging and exciting hunt. He offers Rainsford the chance to join him in the hunt, but Rainsford refuses and becomes the target instead.
The story reaches its climax as Rainsford uses his skills as a hunter to outwit Zaroff and turn the tables on him. In the end, Rainsford emerges as the victor, having proven himself to be the better hunter.
The Most Dangerous Game is a thrilling and suspenseful story that explores the themes of survival, the value of human life, and the dark side of human nature. It highlights the dangerous consequences of allowing one's desires and ego to override moral principles and shows the power of intelligence and resourcefulness in overcoming adversity.
Overall, The Most Dangerous Game is a thought-provoking and entertaining tale that serves as a cautionary warning about the dangers of indulging in dangerous and unethical pursuits.

One fully filled with HCl 5% , another diluted with water so HCl and water were half and half 0. We also controlled the amount of water and the amount of tablets. Determination of a Rate Law Lab Report Abstract: This two part experiment is designed to determine the rate law of the following reaction, 2I- aq + H2O2 aq + 2H+I2 aq + 2H2O L , and to then determine if a change in temperature has an effect on that rate of this reaction. The independent variable is the surface area of the tablets; the dependent variable is the rate that the tablet to dissolve in water and the controlled variables are the amount of water, temperature of water, and the amount of Alka Seltzer tablet 1 tablet each. Nature of Reactants: a The independent variable in the reaction was the type of metal used.

We timed how long it took for the fizzing to stop and the soap to dissolve. There were none extreme results that go against the theory. Drop a piece of Zn into one of the test tubes and time how long the reaction takes. For Part 2, we predicted that the higher concentration the reactants have, the higher the rate of the chemical reaction will be. A series of experiments will be carried out in which only the concentration of the iodide ions will be varied.

Position the 24-well plate to ensure that there are 6 wells down vertical axis and 4 wells across horizontal axis 2. The catalyst test was inconclusive. M to dissolve the metal, and this happened because with the higher concentration, you have more collisions, and with more collisions the reaction happens faster. If we add a catalyst to this reaction, we will increase the reaction rate, thus causing the reaction to speed up. Continue to repeat step 14, of increasing the number of drops of Na 2 S 2 O 3 solution by 1 till it takes approximately 18 — 22 seconds for the solution to appear dark blue 16.
Record the reactions in the table. If it took more than 18 — 22 seconds, repeat the steps 1 — 10 but now using 1 less drop of Na 2 S 2 O 3 solution 13. It turned to black and opaque. We controlled the amount of hydrogen peroxide and the amount of each catalysts to make sure that the change of compounds are the only factor that affect the rate of decomposition. This hypothesis was made according to the information we found in textbook: In the presence of a catalyst, molecules of reactants line up better so that when they collide with each other the reaction is more likely to take place. We made sure that the time were accurate and no other substances were added to the reactants. Discussion of Procedures, Variables and Controls Part 1 In part 1, the procedures we designed were not successfully done due to a shortage of supplies.

H 2 O 2 solution with MnO 2 Transparent and nothing happened. Therefore, these solutions are a suitable series for an examination of the dependence of the rate of reaction on the concentration of the iodide ion. Similarly, solutions C, D, and E have the same concentration of iodide ion. The data between two trials are similar, which proved that there is a very low possibility of wrong data. For Part 4, we predicted that catalysts will affect the rate of the chemical reaction.

Instead of using beakers, we chose to use cylinders in order to prevent overflowing reaction. We followed the procedure closely and f ollowed all the safe ty r ul es. By measuring the time and comparing the results, we would be able to determine whether temperature affects the rate of chemical reactions, if so, how it does so. Mix the solution again by swirling and monitor the colour 10. Add 8 drops of Na 2 S 2 O 3 solution to the KI solution in the same well 6. Note the reaction rate of each and record it in the table.

According to the collision theory, the rate of reaction depends on the frequency of effective collisions between particles. The controlled variables are the amount of hydrogen peroxide and the amount of each catalyst. Is it possible to vary the factors because, in terms of concentration, if we left water in a test tube and we add acid to it, the acidity is going to lower, and it will not be strong enough to react with the metal, and the collision will have already happened with the acid and H2O. Part 3 In part3 of our experiment, we made three Alka Seltzer tablets into different shapes in order to create different surface areas. However, the one thing that remains the same for every reaction is that the more effective collisions there are, the faster the reaction occurs. I would double check the temperature of the water and try to finish the experiment as fast as possible to prevent temperature change. We used thermometer to make sure that both trials have the same temperatures of water.

For the particle size test, I observed that the powdered CaCO3 reacted faster with the hydrochloric acid that the marble chips. Record how fast each reaction occurred. We got the result that the higher the temperature is, the faster the tablet dissolve; the lower the temperature is, the slower the tablet dissolves which completely corresponds to the theory. Instead of using the burner to heat the water, we had to rely on taps to produce three different temperatures of water. We controlled certain variables. Record the reaction rates in the table. Quickly add the H 2 O 2 to the solution in the well, without splashing and as you are doing this, start the stopwatch 9.

Theoretically slivers should have come first because it has more surface area. From the result, we can tell that the time for sodium carbonate to dissolve is much shorter in acetic acid with high concentration than in acetic acid with low concentration. If I repeated the project, I would test some of other c atalysts and their effects to th e rate of reaction. There were no extreme data in our result. Additionally by performing essentially the same experiments but with temperature changes one can determine how k is affected by temperature changes and the new activation energy. Iodine Clock Reaction It is known that ethanol effects hydrogen peroxide and therefore it has an effect on the rate equation. The increase in the concentration showed us this, when the metal dissolved very quickly in a 6.
Also, from graphs the activation energy was determined to be 33. However, when it was dropped into the cold water, it took 3 minutes to dissolve. As the temperature increases, the reaction rate increases due to higher number of collisions 3. Place 8 drops of KI in the top left well 3. The stock solutions are the following: 4 M acetone, 1 M HCl, and 0 M iodine.
