Chapter 12, Problem 53E

Interpretation Introduction

Interpretation: The equilibrium constant value for the reaction between ${\text{N}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$, placed in a flask at an initial pressure of $0.80$ and $0.20\text{atm}$, is given. The partial pressure of $\text{NO}$ is to be calculated.

Concept introduction: The state when the reactants involved in a chemical reaction and the products formed in the reaction exist in concentrations having no further tendency to change is known as an equilibrium state of the reaction. When the equilibrium constant is expressed in terms of pressure, it is represented as $K_{\text{p}}$.

To determine: The partial pressure of $\text{NO}$.
