JEE Main Chemistry question

Hydrogen and oxygen were heated together in a closed vessel. The equilibrium constant is found to decrease after 2000°C. Which is responsible for this?

(A)Backward reaction predominates
(B)Forward reaction predominates
(C)Both forward and backward reactions have the same rate
(D)It is a property of the system, hence no reason for lower valueCorrect

Answer: (D)

Solution

K's decrease with rising T for this exothermic reaction is simply an inherent thermodynamic property (van't
