NEET Chemistry Chemical Equilibrium Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Equilibrium constant expression for a forward reaction | (i) Kc = [PCl3][Cl2] / [PCl5] |
| (b) Inverse of equilibrium constant for reverse reaction | (ii) Kc = 1 / Kc (forward) |
| (c) Effect of adding more reactant on Kc | (iii) Kc remains unchanged |
| (d) Effect of temperature increase on Kc | (iv) Kc may increase or decrease depending on reaction type |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-iv, c-ii, d-iii
a-iv, b-iii, c-i, d-ii
Correct Answer
Detailed Explanation
The equilibrium constant expression for the forward reaction is correctly given as Kc = [PCl3][Cl2] / [PCl5]. The inverse relationship for the reverse reaction is accurately represented by Kc (reverse) = 1 / Kc (forward). Adding more reactant does not change the value of Kc, and the effect of temperature on Kc depends on the specifics of the reaction, which can either increase or decrease Kc based on endothermic or exothermic nature.
