Chapter 5, Problem 5.78P

Interpretation Introduction

(a)

Interpretation:

Calculate the values of the coefficients.

Concept introduction:

The Ideal Gas Law is defined as,

$PV=nRT$

Where, the volume (V) occupied by ‘n’ moles of any gas has a pressure (P) at temperature (T) in Kelvin and ‘R’ = Gas constant

The van der Waals equation of state is given as follows,

$P=\frac{RT}{V-b}-\frac{a}{V^2}$

Here, a and b are van der Waals constants.

Interpretation Introduction

(b)

Interpretation:

Calculate the value of V and estimate the error in calculation.

Concept introduction:

The Ideal Gas Law is defined as,

$PV=nRT$
