Chapter 17, Problem 60A

Interpretation Introduction

Interpretation:

The fact that a reaction proceeds faster when the concentrations of the reactants are increasedhave to be explained by using the collision model.

Concept Introduction:

Collision theory: According to this theory, for a chemical reaction to take place, the collision must occur between the reactant molecules. However, all the collisions are not effective. Only those collisions are effective in result in chemical reaction in which colliding molecules must possess a certain minimum energy called threshold energy.

Explanation of Solution

When the concentration of the reactants is increased the number of reacting molecules is also increased. Therefore more number of collisions between the reactants takes place. Thus the rate of the reaction increases. So, on increasing the concentrations of the reactants, the reaction proceeds at faster rate.
