The change in Gibbs energy for a reaction:
A)= ΔH - TΔS
B)= q (heat)
C)= ΔS + TΔH
D)= ΔS - TΔH
E)= ΔH + TΔS

Question

Quizplus · Accepted Answer

The correct equation for the change in Gibbs energy (ΔG) is ΔG = ΔH - TΔS, where ΔH is the enthalpy change and TΔS is the entropy change. This equation takes into account both the thermodynamic favorability of the reaction (ΔH) and the change in disorder of the system (ΔS).
