Question

State True or False.

In very high pressure region if $Z$ v/s $P$ is plotted at 1200 K for the above gas then it will have greatest slope.

• A. True
• B. False

Answer 1

The correct option is B False

The relationship between $z$ and $P$ is given by the expression $z=1+\frac{Pb}{R{T}^{\prime }}$.
When $z$ is plotted against $P$, the slope is $\frac{b}{RT}$.

Thus the slope is inversely proportional to $T$.
When the temperature is very high such as 1200 K, the slope can not be greatest.
