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 :
Text Solution
Verified by ExpertsThe correct answer is:
A
log K2 = – 2 + log (0.0118) = – 3.928
K2 = 1.18 × 10-4
Therefore, option is correct.
