Question

Compressibility factor $\left(Z\right)$ is plotted against pressure $\left(P\right)$ for four different gases $A,B,C$ & $D$. The correct order of critical temperature of the gases shown in the below graph is

• A. $A>B>C>D$
• B. $B<A<C<D$
• C. $A<B<C<D$
• D. $D<B<C<A$

Answer 1

The correct option is C $A<B<C<D$

Smaller the Z value, more easily the gas can be liquified and the more is the critical temperature. Hence (C) is correct.
