Chapter 11, Problem 9SAQ

Interpretation Introduction

Interpretation: Partial pressure of each gases containing an equal number of moles present in the mixture of gases is to be determined.

Concept Introduction:

In a gas mixture, the pressure due to any individual component is termed as partial pressure of that component.

Any component’s partial pressure is that component’s fractional composition times the total pressure of the mixture.

According to the Dalton’s law of partial pressures, the sum of the partial pressures of each component in a gas mixture must equal the total pressure $\left(P_{\text{Total}}\right)$. This is expressed as:

$P_{\text{Total}}=P_1+P_2+P_3$

Here, $P_1,P_2$ and $P_3$ is the partial pressure of each gas present in the mixture.
