Assertion (A): Vapour pressure of `0.5 M` sugar solution is more than `0.5 M KCl` solution.

Options

A. If both `(A)` and `(R )` are correct, and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R )` is incorrect.
D. If `(A)` is correct, but `(R )` is correct.

Answer

A

Explanation

Lowering of vapour pressure is a colligative property, hence it depends upon the number of solute particles.
