The question given below consist of an assertion and a reason. Use the following key to choose the appropriate answer.

(a) Both Assertion and reason are correct statements, and Reason is the correct explanation of assertion.

(b) Both Assertion and reason are correct statements, and Reason is not the correct explanation of assertion.

(c) Assertion is correct, Reason is the wrong statement.

(d) Assertion is wrong, but Reason is the correct statement.

Assertion: ΔH_mix and ΔV_mix are zero for an ideal solution.

Reason: The interactions between the particles of the components of a solution are almost identical as between particles in the liquids.

(a)

If the intermolecular attractive forces between the A-A and B-B are nearly equal to those between A-B, this leads to the formation of ideal solution.

The ideal solutions have two other important properties. The enthalpy of mixing of the pure components to form the solution is zero and the volume of mixing is also zero, i.e., ∆_mixH = 0, ∆_mixV = 0.
