A system undergoes a process in which the entropy change is . During the process, of heat is added t — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

For a reversible process, $\Delta S = \frac{q_{\text{rev}}}{T} = \frac{1500}{300} = +5.0 \text{ J/K}$. The actual entropy change ($+5.51 \text{ J/K}$) is greater than $\frac{q}{T}$. By Clausius inequality ($\Delta S > \frac{q}{T}$), the process must be irreversible.
