Chapter 6, Problem 89AE

Interpretation Introduction

Interpretation:Value for $K_{\text{p}}$ for below reaction is to be determined.

  $\text{C}\left(s\right)+{\text{CO}}_{\text{2}}\left(g\right)\rightleftharpoons 2\text{CO}\left(g\right)$

Concept introduction:Partial pressure of gas is defined as the product of total pressure with mole fraction of gas. Equilibrium constant for partial pressure is denoted by $K_{\text{p}}$ and is equal to ratio of pressure of product to pressure of reactant. Consider an equilibrium equation as follows:

  $\text{A}\rightleftharpoons \text{B}$

The expression used to calculate $K_{\text{p}}$ is as follows:

  $K_{\text{p}}=\frac{P_{\text{B}}}{P_{\text{A}}}$

Where,

• $K_{\text{p}}$ is equilibrium constant for partial pressure.
• $P_{\text{B}}$ is partial pressure of B (product).
• $P_{\text{A}}$ is partial pressure of A (reactant).
