The dissociation equilibrium of a gas `AB_2` can be represented as, `2AB_2(g) hArr 2AB (g) +B_2(g)`. The degree of disssociation is 'x' and is small compared to 1. The expression relating the degree of dissociation (x) with equilibrium constant `k_p` and total pressure P is

Options

A. `((K_p)/P)`
B. `((2k_p)/P)`
C. `((2K_p)/P)^(1//3)`
D. `((2K_p)/P)^(1//2)`

Answer

C
