As per your syllabus, eqn 5.20-21, GIBBS energy G and its change ΔG at constant T are given by which expressions?
AΔG = q + w
BG = U + pV
CG = H − TS; ΔG = ΔH − T ΔS (at constant T)
DΔG = ΔH + T ΔS
Answer & Solution
Correct answer: C. G = H − TS; ΔG = ΔH − T ΔS (at constant T)
As per your syllabus, eqn 5.20+5.21, G = H − TS (state function).
ΔG = ΔH − TΔS at constant T. Master criterion for spontaneity.
