Question

Assertion: The equilibrium constant(K_p) of the reaction, PCl₅(g) ⇌ PCl₃(g) + Cl₂(g) increases by adding more PCl₅ gas.

Reasoning: Addition of PCl₅ results in shifting of the net reaction towards forward direction till a new equilibrium is set up.

(A) Assertion is True, Reasoning is true, Reasoning is a correct explanation for Assertion.

(B) Assertion is True, Reasoning is true, Reasoning is NOT a correct explanation for Assertion.

(C) Assertion is True, Reasoning is False.

(D) Assertion is False, Reasoning is True.

Answer 1

Correct option is (D) Assertion is False, Reasoning is True.

K_p does not change by adding or removing reacting species in the equilibrium state. It changes only by changing temperature.
