Chapter 9, Problem 34P

Interpretation Introduction

Interpretation: The mole fraction and partial pressure of ${\text{NH}}_{\text{3}}$ is to be calculated with the given information.

  ${\text{N}}_2\left(g\right)+3{\text{H}}_2\left(g\right)\to 2{\text{NH}}_3\left(g\right)$

• Moles of ${\text{NH}}_{\text{3}}$= 13 moles
• Moles of ${\text{N}}_2$= 31 moles
• Moles of ${\text{H}}_2$= 93 moles
• Total pressure = 210 atm

Concept introduction: In a gaseous mixture, the pressure of each component gas is called as partial pressure of that gas. The partial pressure of gas is directly proportional to the mole fraction of the gas. The mathematical expression can be written as:

  $\text{Partial pressure = mole fraction }\times \text{ total pressure}$
