When one mole of A and one mole of B were heated in a one litre flask at T(K), 0.5 moles of C were formed at equilibrium
`A+B hArr C+D`
The equilibrium constant `K_(C)` is

A

0.25

B

0.5

C

1

D

2

Text Solution

Verified by Experts

The correct Answer is:
C

Equilibrium constant`(K_(c)) = [C][D]/([A][B]) = 0.5 xx 0.5/(0.5 xx 0.5) = 1`
