a. Draw a different set of apparatus that could be used to monitor the reaction shown in Figure 9.2.

b. What do we mean by:

i. The activation energy of a reaction?

ii. A catalyst?

c. Does a catalyst work by:

a. Increasing the frequency of collisions?

b. Increasing the proportion of particles with energy greater than the activation energy?

c. Increasing the activation energy?

d. Use the collision theory to explain how increasing the surface area of a solid reactant increases the rate of reaction.
