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
