What happens as you increase the temperature of a reaction?
A. More collisions occur and the time required for the reaction increases.
B. Fewer collisions occur and the time required for the reaction decreases.
C. Fewer collisions occur and the time required for the reaction increases.
D. More collisions occur and the time required for the reaction decreases.

D. More collision occur and the time required for the reaction decreases.

Explanation:

When the temperature of a reaction increases ,the reactant molecules gain more energy, enabling more collisions to occur and thus increasing the rate of the reaction.

An increase in the rate of the reaction means that less time is taken for a reaction to take place.

it's all four options.
