Vedclass · Answer

(C) An ideal solution is defined as a solution that obeys Raoult's law over the entire range of concentration.For an ideal solution, the intermolecular forces of attraction between the components ($P-P$ and $Q-Q$) are similar to the forces of attraction between the mixed components $(P-Q)$.Since the forces of attraction are similar, there is no net change in enthalpy $(\Delta_{mix} H = 0)$ and no net change in volume $(\Delta_{mix} V = 0)$ upon mixing.However, the statement that 'no interactions occur between $P$ and $Q$' is incorrect.In reality, interactions do occur, but the strength of $P-Q$ interactions is equal to the strength of $P-P$ and $Q-Q$ interactions.Therefore, Assertion $A$ is correct, but Reason $R$ is incorrect.

Assertion $A$: For an ideal solution formed by mixing liquids $P$ and $Q$, $\Delta_{mix} H = 0$ and $\Delta_{mix} V = 0$.
Reason $R$: No interactions occur between $P$ and $Q$.
In the light of the above statements, choose the most appropriate answer from the options given below:
