NEET Chemistry Le Chatelier's Principle Assertion Reason Question
Assertion (A): The equilibrium constant Kc for a reaction is not affected by changes in the initial concentrations of reactants. | Reason (R): The concentration of pure solids and liquids is constant and does not appear in the equilibrium constant expression.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
Kc is independent of initial concentrations because it is determined at equilibrium, while the reason refers to the exclusion of pure solids or liquids in the Kc expression, which is unrelated to the effect of initial concentrations.
