Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R) . 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. In the light of the above statements, choose the most appropriate answer from the options given below :

Options

  1. ABoth (A) and (R) are correct but (R) is not the correct explanation of (A).
  2. B(A) is correct but (R) is not correct.
  3. C(A) is not correct but (R) is correct.
  4. DBoth (A) and (R) are correct and (R) is the correct explanation of (A).

Correct answer

B. (A) is correct but (R) is not correct.

Step-by-step solution

- Assertion (A): For any chemical reaction at a particular temperature the equilibrium constant is fixed and is a characteristic property. Correct. At a given temperature, (K ) is constant and unique for the reaction. - Reason (R): Equilibrium constant is independent of temperature. Wrong. Actually, (K ) depends on temperature (Van't Hoff equation shows this).
