Question
The equilibrium constant for, 2H2S (g) ⇋ 2H2(g) + S2(g) is 0.0118 at 1300 K while the heat of dissociation is 597.4 kJ. The standard equilibrium constant of the reaction at 1200 K is :
Options
A.1.180 × 10-4
B.11.80
C.118.0
D.cannot be calculated from given data
Solution
log 
log
log K2 = - 2 + log (0.0118) = - 3.928 ⇒ K2 = 1.18 × 10-4
Therefore, (A) option is correct.
