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 exothermic reaction decreases because the entropy change of the system is positive
B
With increase in temperature, the value of $$K.$$ for endothermic reaction increases because unfavorable 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 favorable change in entropy of the surroundings decreases
