Assertion For the reaction, N (g) 3H (g) 2NH (g) Unit of Kc = L2 mol–2 Reason For the reaction N (g) 3H (g) 2NH (g) Equilibrium constant, c [NH ] K [N ][H ] (AIIMS 2008)
A.Both Assertion and Reason are true and Reason is✓ Correct
B.Both Assertion and Reason are true and Reason is
C.Assertion is true but Reason is false.
D.Both Assertion and Reason are false.
Explanation
The given reaction is: 2 2 3 N (g) 3H (g) 2NH (g) CHEMICAL EQUILIBRIUM 57 The expression of equilibrium constant will be 2 3 c 3 2 2 [NH ] K = [N ][H ] And the concentration is expressed in mol per liters Hence, the unit of 2 -2 c K =L mol Hence, the correct answer is option (a)
