Chapter 5, Problem 5.114P

(a)

Interpretation Introduction

Interpretation:

The lower flammable limit for ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}\left(l\right)$ is to be calculated.

Concept introduction:

According to Avogadro’s law, the volume occupied by the gas is directly proportional to the mole of the gas at the constant pressure and temperature.

The relationship between volume and mole can be expressed as follows,

$\text{V }\alpha n$

Here, $n$ is the mole of the gas and $V$ is the volume.

The ideal gas equation can be expressed as follows,

$PV=nRT$

Here, $P$ is the pressure, $V$ is the volume, $T$ is the temperature, $n$ is the mole of the gas and $R$ is the gas constant.

(b)

Interpretation Introduction

Interpretation:

The volume of ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}\left(l\right)$ is required to produce a flammable mixture of hexane in $\text{1}{\text{.000 m}}^{\text{3}}$ air is to be calculated.

Concept introduction:

The ideal gas equation can be expressed as follows,

$PV=nRT$

Here, $P$ is the pressure, $V$ is the volume, $T$ is the temperature, $n$ is the mole of the gas and $R$ is the gas constant.
