Chapter 8, Problem 51QRT

Interpretation Introduction

Interpretation:

Partial pressure of $H_2$ has to be determined using the given data.

Concept Introduction:

Dalton’s law of partial pressure:

According to this law, the total pressure exerted by each gas in a mixture is equal to the sum of the individual partial pressure of the gases.

Partial pressure: It is the pressure of each gas in a mixture of gases.

Mole fraction: Quantity which defines the number of moles of a substance in a mixture divided by the total number of moles of all substances present.

${\text{X}}_{\text{a}}\text{=}\frac{{\text{n}}_{\text{a}}}{{\text{n}}_{\text{total}}}$

Partial pressure of a gas in the mixture of gases is the product of mole fraction of the gas and the total pressure.

  ${\text{P}}_{\text{a}}\text{=}{\text{X}}_{\text{a}}\text{×}{\text{P}}_{\text{total}}$
