Ncert Exercises & Solutions

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.

1.	Both (A) and (R) are true and (R) is the correct explanation of (A).
2.	Both (A) and (R) are true but (R) is not the correct explanation of (A).
3.	(A) is true but (R) is false.
4.	(A) is false but (R) is true.

Hint: The equilibrium constant of a reaction depends upon temperature.

Equilibrium constants are changed if we change the temperature of the system. For any chemical reaction at a particular

temperature, the equilibrium constant is fixed and is a characteristic property. Hence, Assertion is true but the reason is false.
