Chapter 15, Problem 77AE

Interpretation Introduction

Interpretation:

The value of $K_{\text{p}}$ for the reaction at ${\text{150 }}^{\text{ο}}\text{C}$ and the pressure of $\text{IBr}$ is given. The partial pressure of all substances after reaching equilibrium is to be calculated.

Concept introduction: The equilibrium constant ( $K_{\text{p}}$ ) is used when reactants and products in a chemical reaction are gases. The numerical value of $K_{\text{c}}$ is generally different from $K_{\text{p}}$ .

To determine: The partial pressure of all substances after reaching equilibrium.
