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

`"Intial moles Moles at equili", underset(1-x)underset(1)(A)+underset(1-x)underset(1)(B)rArrunderset(x)underset(0)(C ) + underset(x)underset(0)(D)`
`"Given", " " x = 0.5 mol`
`therefore " " (1-x) = 0.5 mol`
`rArr " " K_( C) =([C][D])/([A][B])=(0.5xx0.5)/(0.5xx0.5)=1`
