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 unfavourable change in entropy of the surroundings decreases
  • c)
     With increase in temperature, the value of K for exothermic reaction decreases because favourable change in entropy of the surroundings decreases
  • d)
     With increase in temperature, the value of K for endothermic reaction increases because the entropy change of the system negative
Correct answer is option 'B,C'. Can you explain this answer?

- **Effect of Temperature on Equilibrium Constant K**

Increasing temperature can have a significant impact on the equilibrium constant K for a reaction in equilibrium with its surroundings. This effect is described in terms of the change in entropy of the system and the surroundings.

- **Exothermic Reaction (Option C)**

- **Explanation:** For an exothermic reaction, the value of K decreases with an increase in temperature. This is because the favorable change in entropy of the surroundings decreases at higher temperatures.

- **Endothermic Reaction (Option B)**

- **Explanation:** In the case of an endothermic reaction, the value of K increases as the temperature rises. This is because the unfavorable change in entropy of the surroundings decreases with an increase in temperature.

Therefore, both options B and C accurately describe the effect of temperature on the equilibrium constant K for exothermic and endothermic reactions, respectively. Understanding these relationships is crucial in predicting how changes in temperature can influence the equilibrium position of a chemical reaction.
