Question

Which of the following is necessary to increase the rate of a reaction? A. a decrease in the frequency of collisions B. an increase in the frequency of collisions C. a decrease in the frequency of successful collisions D. an increase in the frequency of successful collisions

Answer 1

To increase the rate of a reaction, D. an increase in the frequency of successful collisions is necessary. As the collision that are successful, that is molecules collide with energy that is sufficient to break a chemical bond or that collide with proper orientation that can only increase the rate of the reaction.

So the answer is  D. an increase in the frequency of successful collisions is necessary

Answer 2

The correct answer is

D- an increase in the frequency of successful collisions
