Chapter 15, Problem 69E

Interpretation Introduction

Interpretation:

The effect of given changes in volume on the following reaction at equilibrium is to be predicted.

${\text{I}}_{\text{2}}\left(\text{g}\right){\text{ + Cl}}_{\text{2}}\left(\text{g}\right)\underset{}{\overset{}{\rightleftarrows }}\text{ 2ICl}\left(\text{g}\right)$

Concept Introduction:

The inverse relation between the volume and the pressure. $\text{P }\propto \frac{\text{1}}{\text{V}}$

If the volume increases, pressure will decrease and if the volume decreases, pressure will increase.

If volume increases, the equilibrium reaction mixture will shift towards the side of higher number of moles. But if volume decrease, the equilibrium reaction mixture will shift towards side of the lesser number of moles.
