Chapter 13.10, Problem 13.21P

Interpretation Introduction

Interpretation:

The effect of change in temperature of given reaction results in change in ${\text{K}}_{\text{c}}$ and moles of ethyl acetatehas to beexplained.

Concept introduction:

Le Chatelier's principle states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.

Effect of change in temperature:

Endothermic reaction:

In this reaction increase in temperature which is absorbed in reactant side, the reaction occurs in a way to relieve the stress in reactant side. The reaction occurs along the direction of product side and increases equilibrium constant.

Exothermic reaction:

In this reaction increase in temperature which is released in product side, the reaction occurs in a way to relieve the stress in product side. The reaction occurs along the direction of reactant side and decreases equilibrium constant.
