Vedclass · Answer

(B) The van der Waals equation is given by $(P + \frac{an^2}{V^2})(V - nb) = nRT$. For $1 	ext{ mole}$ of gas,it becomes $(P + \frac{a}{V^2})(V - b) = RT$. At low pressure,the volume $V$ is very large,so $b$ is negligible compared to $V$. At high temperature,the term $\frac{a}{V^2}$ becomes negligible because $V$ is large. Thus,the equation simplifies to $PV = RT$,which is the ideal gas equation.

The van der Waals equation reduces to the ideal gas equation under which of the following conditions?
