Chapter 12, Problem 70QP

Interpretation Introduction

Interpretation:

The reason that the position of the equilibrium is product-favored at $25°\text{C}$ but reactant-favored at $500°\text{C}$ is to be stated.

Concept Introduction:

The equilibrium rate is highly affected by a change in temperature.

In an endothermic reaction, the equilibrium shifts toward the right with an increase in temperature.

In the case of an exothermic reaction, heat is released; so, an increase in temperature shifts the equilibrium toward the left.
