1. List the four variables or factors that can affect the rate of reaction.

Which of the following statements is the best explanation of how activation energy affects the rate of a chemical reaction?   A. A high activation energy means molecules have less kinetic energy and hence rate of reaction will be slower.   B. A high activation energy means molecules must have more kinetic energy to overcome it, and hence rate of reaction will be faster.   C. A high activation energy means molecules have a lot of kinetic energy and hence rate of reaction will be faster.     D. A high activation energy means molecules must have less kinetic energy to overcome it, and hence rate of reaction will be slower.   E. A high activation energy means molecules must have more kinetic energy to overcome it, and hence rate of reaction will be slower.

List the four things, other than the nature of reactants, that can speed up reaction rate AND briefly describe how for each one.

What are three factors that affect ' rate of reactions'
