Equivalent amounts ofH2 and I2are heated in a closed vessel till equilibrium is obtained. If 80% of the hydrogen can be converted to HI, the K c at this temperature is

Options:

Answer:
A
Solution:

Let here be 1M each of H2and I2
H2              +   I2              2HI
1                       1                  0
(1-0.8)           (1-0.8)2×0.8
=0.2                =0.2              =1.6
K c = HI 2 H 2 I 2
 = 1.6×1.6 0.2×0.2
K c =64
