Chapter 20, Problem 112CP

(a)

Interpretation Introduction

Interpretation: It is given that, nitrogen reacts with hydrogen gas (in a container) to produce ammonia gas. The volume of this mixture and total pressure is given. The partial pressure and mole fraction of ammonia in a container during completion of reaction is to be calculated. The volume of container during the completion of reaction is to be calculated.

Concept introduction: The volume is calculated using ideal gas law,

$PV=nRT$

The mole fraction of ammonia is calculated using the formula,

$\text{Mole}\text{fraction}\text{of}{\text{NH}}_3=\frac{\text{Moles }{\text{of NH}}_3}{{\text{Moles of N}}_2+{\text{Moles of NH}}_3}$

To determine: The partial pressure of ammonia in a container during completion of reaction.
