Chapter 11.6, Problem 11.10WE

Interpretation Introduction

Interpretation:

The pressure of the gas calculated using the ideal gas equation and the van der Waals equation has to be explained.

Concept introduction:

Ideal gas is the most usually used form of the ideal gas equation, which describes the relationship among the four variables $\text{P, V, n, and T}\text{.}$  An ideal gas is a hypothetical sample of gas whose pressure-volume-temperature behavior is predicted accurately by the ideal gas equation.

                              $\text{PV = nRT}$

Van der Waals equation:

We find the pressure by first solving algebraically for $\text{P}\text{.}$

$\text{P=}\frac{\text{nRT}}{\text{V-nb}}\text{-}\frac{{\text{an}}^{\text{2}}}{{\text{V}}^{\text{2}}}$
