For a reaction taking place in a container in equilibrium with its surroundings, the effect of temperature on its equilibrium constant K in terms of change in entropy is described by
- with increase in temperature, the value of K for endothermic reaction increases because unfavourable change in entropy of the surroundings decreases
- with increase in temperature, the value of K for exothermic reaction decreases because favourable change in entropy of the surroundings decreases
- with increase in temperature, the value of K for exothermic reaction decreases because the entropy change of the system is positive
- with increase in temperature, the value of K for endothermic reaction increases because the entropy change of the system is negative.
Answer
(A) with increase in temperature, the value of K for endothermic reaction increases because unfavourable change in entropy of the surroundings decreases
