Chapter 6, Problem 93AE

Interpretation Introduction

Interpretation:Partial pressure of m:math display='block'>NO2(g) and ${\text{N}}_2{\text{O}}_4\left(g\right)$ at equilibrium is to be determined.

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 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).
