Chapter 6, Problem 89E

Interpretation Introduction

Interpretation:

The radius of one helium atom in picometershould be calculated with the help of van der Waals constant ‘b’.

Concept introduction:

The mathematical equation of Vander Waals equation can be written as:

$\left(\text{P + }\frac{{\text{n}}^{\text{2}}\text{a}}{{\text{V}}^{\text{2}}}\right)\left(\text{V- n b}\right)\text{ = nRT}$

Here ‘a’ and ‘b’ are the Vander Waal’s constants. The Vander Waals constant ‘a’ is the pressure correction whereas ‘b’ is the volume correction in the equation.
