Chemistry Thermodynamics and Thermochemistry JEE Advanced Previous Years Question Single Correct MCQ
Published on: August 14, 2026

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

A
With increase in temperature, the value of K for endothermic reaction increases because unfavourable change in entropy of the surroundings decreases
B
With increase in temperature, the value of K for exothermic reaction decreases because favourable change in entropy of the surroundings decreases
C
With increase in temperature, the value of K for endothermic reaction increases because the entropy change of the system is negative
D
With increase in temperature, the value of K for exothermic reaction decreases because the entropy change of the system is positive
