Chapter 14, Problem 14.74QP

(a)

Interpretation Introduction

Interpretation: The change in the partial pressure of $\text{NO}$ and ${\text{NO}}_2$ is to be predicted given the change in the partial pressure of ${\text{O}}_2$ is $-x$. The total pressure in the reaction vessel is to be calculated.

Concept introduction: The equilibrium constant $\left(K_{\text{p}}\right)$ is expressed as,

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

To determine: The change in the partial pressure of $\text{NO}$ and ${\text{NO}}_2$.

(b)

Interpretation Introduction

To determine: The total pressure in the reaction vessel.
