Chemical Thermodynamics: JEE Main 2026 Chemistry question

Match the LIST-I with LIST-II. LIST-I (Isothermal process for ideal gas system): (A) Reversible expansion; (B) Free expansion; (C) Irreversible expansion; (D) Irreversible compression. LIST-II (Work done, $V_f > V_i$): (I) $w = 0$; (II) $w = -nRT\ln\frac{V_f}{V_i}$; (III) $w = -p_{ex}(V_f - V_i)$; (IV) $w = -p_{ex}(V_i - V_f)$. Choose the correct answer from the options given below:
