Question

The degree of dissociation of SO3 is α at equilibrium pressure P0.
    Kp for 2SO3(g)  ⇋  2SO2(g) + O2(g) is

Options

A.[(P0α3)/2(1 - α)3]
B.[(P0α3)/(2+α)(1 - α)2]
C.[(P0α2)/2(1 - α)2]
D.None of these

Solution

2SO3(g)  ⇋   2SO2 (g)    +    O2(g)
t = 0     a            0        0
t = teq.   a(1-α)            aα        a
Total mole at eq.
PSO3 = × Po
PSO2 = × Po
PO2 = Po
