Question

At a temperature T, a compound AB4(g) dissociates as 2AB4(g) ⇋ A2(g) + 4B2(g) with a degree of dissociation x, which is small compared with unity. The expression of KP in terms of x and total pressure P is ;

Options

A.8P3x5
B.256P3x5
C.4Px2
D.None of these

Solution

2AB4(g) ⇋ A2(g) + 4B2(g)    ∑ n = 1 +    ≃  1
1 - α               2x    1 - α ≃ 1
KP = = 8P3α5
