JEE Main2026Jan 22, Shift 1Chemistry

Given below are two statements:

Statement I : The Henry’s law constant $K_{H}$ is constant with respect to variations in solution’s concentration over the range for which the solutions is ideally dilute.

Statement II : $K_{H}$ does not differ for the same solute in different solvents.

In the light of the above statements, choose the correct answer from the options.

A
Statement I is false but Statement II is true.
B
Statement I is true but Statement II is false.
C
Both Statement I and Statement II are true.
D
Both Statement I and Statement II are false.

Solution

Statement I — Henry’s law $p = K_{H} x$ is a limiting law for dilute solutions; in the ideally-dilute regime, $K_{H}$ is constant with respect to concentration. True.

Statement II — $K_{H}$ depends strongly on the nature of both the solute and the solvent (different intermolecular interactions). For the same solute in different solvents, $K_{H}$ differs. False.
