Match Column I with Column II — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

(A) Isothermal for ideal gas means $\Delta U = \Delta H = 0$; reversible means $\Delta S_{\text{total}} = 0$ (Q). (B) Adiabatic means $q = 0$ (S); reversible means no net entropy generation (P). (C) Adiabatic means $q = 0$ (S); free expansion is irreversible, creating net entropy ($\Delta S_{\text{total}} > 0$, R).
