Chapter 5, Problem 5.110PAE

Interpretation Introduction

Interpretation: To determine the information needed to calculate the partial pressure of hydrogen

Concept introduction:

According to the Dalton’s law of partial pressure, “the total pressure of a mixture of gases is given by the sum of partial pressures of individual gases”. And relation between partial pressure and total pressure is given by the equation:

$\begin{array}{l}{\text{P}}_{\text{i}}{\text{=X}}_{\text{i}}{\text{P}}_{\text{total}}\\ \end{array}$

Where

${\text{P}}_{\text{i}}\text{=}$ partial pressure

${\text{X}}_{\text{i}}$ =mole fraction of the component gas

${\text{P}}_{\text{total}}$ =total pressure of the gas

Given:

$H_2$ is produced from the reaction of an acid with zinc.

Heat is given off.
