For an ideal solution formed by mixing two liquids $P$ and $Q$ , the enthalpy of mixing ( $Δ_{mi x} H$ ) and the volume of mixing ( $Δ_{mi x} V$ ) are both zero. Thus, Assertion $A$ is correct.

In an ideal solution, the intermolecular attractive forces between the solute and solvent molecules ( $P-Q$ interactions) are of the same magnitude as those between the pure components ( $P-P$ and $Q-Q$ interactions). It is incorrect to state that no interactions occur between $P$ and $Q$ . Thus, Reason $R$ is not correct.

Therefore, $A$ is correct but $R$ is not correct.
