Chapter 15, Problem 89AE

Interpretation Introduction

Interpretation:

An equilibrium mixture of ${\text{H}}_{\text{2}}$ , ${\text{I}}_{\text{2}}$ , $\text{HI}$ and their moles in a $\text{5 L}$ vessel are given. The equilibrium partial pressures when equilibrium is reestablished following the addition of $\text{0}\text{.200 mol}$ of $\text{HI}$ are 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 equilibrium partial pressures when equilibrium is reestablished following the addition of $\text{0}\text{.200 mol}$ of $\text{HI}$ .
