NEET Chemistry Le Chatelier's Principle Assertion Reason Question
Assertion (A): The addition of potassium thiocyanate to a solution containing [Fe(SCN)]²⁺ increases the red color intensity. | Reason (R): The addition of potassium thiocyanate shifts the equilibrium to the right, increasing the concentration of [Fe(SCN)]²⁺.
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.
Correct Answer
Detailed Explanation
The addition of potassium thiocyanate increases the concentration of SCN⁻, which shifts the equilibrium to the right, thus increasing [Fe(SCN)]²⁺ and the red color intensity.
