The enthalpy and entropy change for a chemical reaction are –2500 cal and +7.4 cal/K, respectively. — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

$\Delta G = \Delta H - T\Delta S = -2500 - 298(7.4) = -2500 - 2205.2 = -4705.2\text{ cal}$. Since $\Delta G$ is highly negative (less than zero), the process is inherently spontaneous.
