What will happen to the reaction system if there is an increase in temperature?
a. More collisions occur, but the collision energy is the same.
b. More collisions will occur, resulting in a higher reaction rate.
c. The same number of collisions occurs with the same collision energy.
d. The same number of collisions occur but with greater collision energy.

Answer:
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
