JEE Main 2026 Jan 22 Shift 1, Chemistry Q20: Vapour Pressure Of A Solution

JEE Main2026Jan 22, Shift 1Chemistry
Q.

Given below are two statements:

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

Statement II : does not differ for the same solute in different solvents.

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

  1. A

    Statement I is false but Statement II is true.

  2. B

    Statement I is true but Statement II is false.

  3. C

    Both Statement I and Statement II are true.

  4. D

    Both Statement I and Statement II are false.

Solution

Statement I — Henry’s law is a limiting law for dilute solutions; in the ideally-dilute regime, is constant with respect to concentration. True.

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