Match items in List I with items in List II

Choose the correct answer from the options given below.
Step 1: Understand each process and corresponding work done.
Let’s review the work done for each thermodynamic process: Isothermal process (A): In this process, the temperature remains constant. The work done is given by: \[ W = \mu RT \ln \left( \frac{V_2}{V_1} \right) \] Hence, the correct matching for A is III. Adiabatic process (B): In this process, there is no heat exchange, and the work done is related to the change in temperature by the formula: \[ W = \mu R \frac{(T_1 - T_2)}{(y - 1)} \] Hence, the correct matching for B is IV. Isochoric process (C): In this process, the volume is constant, so no work is done. Therefore, the work done is zero. Hence, the correct matching for C is I. Isobaric process (D): In this process, the pressure is constant, and the work done is given by: \[ W = \mu RT(T_2 - T_1) \] Hence, the correct matching for D is II.
Step 2: Conclusion.
The correct answer is (1) A-III, B-IV, C-I, D-II.

The standard heat of formation, in kcal/mol, of $Ba^{2+}$ is:
Given: Standard heat of formation of SO₄²⁻(aq) = -216 kcal/mol, standard heat of crystallization of BaSO₄(s) = -4.5 kcal/mol, standard heat of formation of BaSO₄(s) = -349 kcal/mol.
