Chapter 23, Problem 26E

Interpretation Introduction

Interpretation: The partial pressure of $\text{NOCl}$ at equilibrium is to be calculated.

Concept introduction: The equilibrium constant is the ratio of equilibrium concentration or partial pressure of products to the reactants with each term raised to the power of their coefficient in the balanced chemical equation. For the general reaction,

$a\text{A}\left(g\right)+b\text{B}\left(g\right)\stackrel{}{\rightleftharpoons }c\text{C}\left(g\right)+d\text{D}\left(g\right)$

The equilibrium constant is given as:

$K_p=\frac{{\left(P_{\text{C}}\right)}^c{\left(P_{\text{D}}\right)}^d}{{\left(P_{\text{A}}\right)}^a{\left(P_{\text{B}}\right)}^b}$
