Chapter 9, Problem 68QP

Interpretation Introduction

Interpretation:

The relation between the volume of gaseous reactants and products when temperature and pressure are constant is to be determined.

Concept Introduction:

When the temperature and pressure of a gas are constant, then the volume of the gas $\left(V\right)$ depends upon the number of molecules $\left(n\right)$ present in the gas. As the number of molecules of a gas increases, the volume of the gas also increases at constant temperature and pressure.

$\begin{array}{c}V\propto n\\ \frac{V_1}{n_1}=\frac{V_2}{n_2}\mathrm{......}\left(1\right)\end{array}$

Here $V_1$ , $n_1$ represent the initial volume and number of moles of gas. $V_2$ , $n_2$ represent the final volume and number of moles of gas.
