Question

As the number of effective collisions between reacting particles increases, what happens to the rate of reaction?

Answer 1

As the number of effective collisions between reacting particles increases, the rate of reaction increases.

Explanation:

In order for a chemical reaction to occur and products to be formed, the elements that make up those products must physically come in contact with each other.

The more the constituent particles are colliding, the faster product is forming.

This is a reason why raising the temperature, and thereby increasing the kinetic energy of the reactants, causes a reaction to speed up.
