Chapter 1, Problem 1C.1E

Interpretation Introduction

Interpretation:

The critical point of ammonia gas occurs at $111.3atm,72.5c{m}^{3}mo{l}^{-1}$ and temperature has $405.5K$. Using the given data’s the compression factor at the critical point should be calculated.

Concept Introduction:

Ideal gas Equation:

Any gas is described by using four terms namely pressure, volume, temperature and the amount of gas. Thus combining three laws namely Boyle’s, Charles’s Law and Avogadro’s Hypothesis the following equation could be obtained. It is referred as ideal gas equation.

  $\begin{array}{l}\text{V }\propto \frac{\text{nT}}{\text{P}}\\ \text{V = R}\frac{\text{nT}}{\text{P}}\\ \text{PV = nRT}\end{array}$       $\begin{array}{l}\text{where,}\\ \text{n = moles}\text{of}\text{gas}\\ \text{P = pressure}\\ \text{T = temperature}\\ \text{R = gas }\text{constant}\text{and }\text{V=}\text{Volume}\end{array}$
