हिन्दीAt constant pressure and temperature, the entropy change of the surroundings is related to the system's enthalpy change by which expression?
View Answer & Solution
Correct answer · Option C
\( \Delta S_{\text{surr}} = -\frac{\Delta H_{\text{sys}}}{T} \)
Explanation
Heat absorbed by surroundings is \( q_{\text{surr}} = -\Delta H_{\text{sys}} \), so \( \Delta S_{\text{surr}} = \frac{q_{\text{surr}}}{T} = -\frac{\Delta H_{\text{sys}}}{T} \).
