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

Answer»

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 endothermic reaction increases because the entropy change of the system is negative
With increase in temperature, the value of K for exothermic reaction decreases because the entropy change of the system is positive

Solution :`DeltaS_("Surr")=(-DeltaH)/(T_("Surr"))`
For endothermic, if `T_("surr")` increases, `DeltaS_("surr")` will increases.
For exothermic, if `T_("surr")` increases, `DeltaS_("surr")` will decreases.
