Question

How is the change in Gibbs free energy (Delta G) related to the entropy change of the universe (Delta S_univ) at constant T and P?
Options
A Delta G = Delta S_univ / T
B Delta G = -T * Delta S_univ
Correct Answer
C Delta G = T * Delta S_univ
D Delta G = -Delta S_univ / T
Correct Answer

Option B is the correct answer.

Detailed Explanation

Multiplying Delta S_univ = Delta S_sys - (Delta H_sys / T) by -T gives -T * Delta S_univ = Delta H_sys - T * Delta S_sys = Delta G.
