Question
Assertion A: For an ideal solution formed by mixing liquids $\mathbf{P}$ and $\mathbf{Q},\Delta_{\text{mix}\text{~}}\mathbf{H} = 0$ and $\Delta_{\text{mix}\text{~}}V = 0$
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.
Options
A.$\mathbf{A}$ is correct but $\mathbf{R}$ is not correct
B.$\mathbf{A}$ is not correct but $\mathbf{R}$ is correct
C.Both A and R are correct and R is the correct explanation of A
D.Both A and R are correct but R is NOT the correct explanation of A
Solution
Sol. [Key Concept: Ideal solution — ΔmixH = 0, ΔmixV = 0]
For ideal solution, $\Delta_{\text{mix}\text{~}}H = 0$ and $\Delta_{\text{mix}\text{~}}V = 0$
In ideal solution energy required to break interaction between P-P and Q-Q will be same as the energy released on the interaction of P-Q.
