Given the value of their van der Waals constant ‘a’ arrange the following gases in the order of their expected liquification pressure at a temperature T. T is below the critical point of all the gases.

Gas CH₄ Kr N₂ Cl₂

‘a’ 2.283 2.439 1.408 6.579

(atm L².mol^–1)

(A) CH₄ < Kr < N₂ < Cl₂

(B) N₂ < CH₄ < Kr < Cl₂

(C) Cl₂ < Kr < CH₄ < N₂
