Question
Assertion (A): For any chemical reaction at a particular temperature, the equilibrium constant is fixed and is a characteristic property.
Reason (R): Equilibrium constant is independent of temperature.
Options
Both A and R are true and R is correct explanation of A.
Both A and R are true but R is not correct explanation of A.
A is true but R is false.
Both A and R are false.
Solution
A is true but R is false.
Explanation:
The equilibrium constant for an exothermic reaction (negative H) decreases as the temperature increases. The equilibrium constant for an endothermic reaction (positive H) increases as the temperature increases.
