Chapter 3, Problem 3E.9E

(a)

Interpretation Introduction

Interpretation:

Pressure exerted by $1.00{\text{ mol H}}_2\text{S}$ when it behaves as ideal gas has to be determined.

Concept Introduction:

The expression for ideal gas equation for one mole of gas is as follows:

  $PV=RT$        (1)

Here,

$P$ is pressure of gas.

$V$ is molar volume of gas.

$T$ is absolute temperature of gas.

$R$ is universal gas constant.

(b)

Interpretation Introduction

Interpretation:

Pressure exerted by $1.00{\text{ mol H}}_2\text{S}$ when it behaves as van der Waals gas has to be determined.

Concept Introduction:

The formula to calculate pressure of one mole of gas is as follows:

  $P=\frac{RT}{\left(V-b\right)}-\frac{a}{V^2}$        (3)

Here,

$P$ is pressure of gas.

$V$ is volume of gas.

$T$ is absolute temperature of gas.

$R$ is universal gas constant.

$a$ and $b$ are van der Waals parameters.
