Four gases P, Q, R and S have almost same values of ‘b’ but their ‘a’ values (a, b are van der Waals constants) are in the order Q

Question

Four gases P, Q, R and S have almost same values of ‘b’ but their ‘a’ values (a, b are van der Waals constants) are in the order Q < R < S < P. At a particular temperature, among the four gases the most easily liquefiable one is (A) P (B) Q (C) R (D) S

Higher the value of a, more will be the tendency to get liquefy. Since, value of a is highest for P1 thus, P is the most liquefiable gas among the given.

Q. Four gases $P, Q, R$ and $S$ have almost same values of ‘b’ but their ‘a’ values (a, b are van der Waals constants) are in the order $Q < R < S < P$ . At a particular temperature, among the four gases the most easily liquefiable one is

Higher the value of $a$ , more will be the tendency to get liquefy. Since, value of $a$ is highest for $P_{1}$ thus, $P$ is the most liquefiable gas among the given.
