Chapter 3, Problem 3C.1BST

Interpretation Introduction

Interpretation:

Partial pressure of each gas produced after hydrolysis of water has to be determined.

Concept Introduction:

Dolton’s law of partial pressure gives relation between total pressure of mixture of gases and partial pressure of individual gases. The expression of relation can be represented as follows:

  $P=P_{\text{A}}+P_{\text{B}}+\cdot \cdot \cdot$

Here,

A and B are individual gases.

$P_{\text{A}}$ is partial pressure of gas A.

$P_{\text{B}}$ is partial pressure of gas B.

$P$ is total pressure of mixture of gases.

Mole fraction is a relation between moles of constituent and total moles of all constituent in mixture. The expression of relation can be represented as follows:

  $x_{\text{A}}=\frac{n_{\text{A}}}{n}$

Here,

$x_{\text{A}}$ is mole fraction of gas A.

$n_{\text{A}}$ aremoles of gas A.

$n$ is sum moles of all gases.
