Solution
The correct option is CK21=K2 The equilibrium constants of the reactions, SO2(g)+12O2(g)⇌SO3(g) and 2SO2(g)+O2(g)⇌2SO3(g) are K1 and K2 respectively. The relationship between K1 and K2 is K21=K2. It can also be represented as K1=K1/22. K1=[SO3][SO2][O2]1/2 K2=[SO3]2[SO2]2[O2] K2=([SO3][SO2][O2]1/2)2 K2=K21
