The dissociation equilibrium of a gas AB, can be represented as
2AB2(g) ⇌ 2AB(g) +B2 (g)
The degree of dissociation is x and is small compared to 1. The expression relating the degree of dissociation (x) with equilibrium constant Kp and total pressure p is
(a) (2Kp/p)1/2
(b) kp/p
(c) 2kp/p
(d) (2kp/p)1/3
