Chapter 5, Problem 5.123SP

Interpretation Introduction

Interpretation:

The given reaction the percent error made in using the ideal gas equation to calculate the pressure has to be calculated.

Concept Introduction:

Ideal gas is the most usually used form of the ideal gas equation, which describes the relationship among the four variables P, V, n, and T.  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

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

The percent error formula

$\text{\%}\text{error}\text{=}\frac{\left|{\text{P}}_{\text{vdW}}{\text{-P}}_{\text{ideal}}\right|}{{\text{P}}_{\text{vdW}}}\text{×100\%}$
