Chapter 17, Problem 56A

Interpretation Introduction

Interpretation:

The fact that the collision among the molecules is only consideration for the molecules to react with one another has to be explained.

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

For the molecules to react with one another, the reactant molecules should collide in a favourable orientations and colliding molecules must possess a certain minimum energy called threshold energy. 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.
