1. Reaction rate is the change in the amount of products or reactants in a given amount of time.

a. List and explain briefly the four factors that can affect the rate of a chemical reaction.

b. What information is necessary to relate reactants disappearance rate to the rate of appearance of products?

2. The central idea of the collision model is that molecules must collide to react.

a. What factors determine whether a collision between two molecules will lead to a chemical reaction?

b. According to the collision model, why does temperature affect the value of the rate constant, k?

c. The Arrhenius equation can relate the rate constant, k and temperature. Which part of the equation illustrates this relationship? Explain your answer.
