Question
The enthalpy and entropy change for a chemical reaction are −2500 cal and +7.4 cal/K, respectively. The nature of reaction at 298 K is
Options
A.spontaneous
B.reversible
C.never occurring
D.non-spontaneous
Solution
$\Delta G = \Delta H - T.\Delta S = ( - 2500) - 298 \times ( + 7.4) = - ve \Rightarrow \text{Spontaneous}$
