Jee Advanced 2026 Thermodynamics PYQ with Solution

Question

List-I contains various physical/chemical processes, and List-II contains combinations of changes in enthalpy ($\Delta H$) and entropy ($\Delta S$). Match each entry in List-I to the appropriate entry in List-II, and choose the correct option.

List-I	List-II
(P) Physisorption	(1) $\Delta H > 0 \text{ and } \Delta S > 0$
(Q) Diamond $\rightarrow$ Graphite	(2) $\Delta H < 0 \text{ and } \Delta S < 0$
(R) Denaturation of protein	(3) $\Delta H < 0 \text{ and } \Delta S = 0$
(S) Propene $\rightarrow$ Cyclopropane	(4) $\Delta H > 0 \text{ and } \Delta S < 0$
	(5) $\Delta H < 0 \text{ and } \Delta S > 0$
