Q6 / 75 · JEE Main 2025 (3 Apr Shift 1) · Chemistry
Given below are two statements
Statement I : A catalyst cannot alter the equilibrium constant $\left(\mathrm{K}_{\mathrm{c}}\right)$ of the reaction, temperature remaining constant
Statement II : A homogenous catalyst can change the equilibrium composition of a system temperature remaining constant
In the light of the above statements, choose the correct answer from the options given below
Statement I : A catalyst cannot alter the equilibrium constant $\left(\mathrm{K}_{\mathrm{c}}\right)$ of the reaction, temperature remaining constant
Statement II : A homogenous catalyst can change the equilibrium composition of a system temperature remaining constant
In the light of the above statements, choose the correct answer from the options given below
- AStatement I is false but Statement II is true
- Correct answerBBoth Statement I and Statement II are true
- CBoth Statement I and Statement II is false
- DStatement I is true but Statement II is false
Solution
A catalyst can change equilibrium composition if it is added at constant pressure, but it can not change equilibrium constant.
Hence, the correct answer is option: 'B'.
