Question

Which of the following conditions would predict a process that is always
spontaneous?
(i) ΔH > 0, Δ S > 0
(ii) Δ H > 0, Δ S < 0
(iii) Δ H < 0, Δ S > 0
(iv) Δ H < 0, Δ S < 0

Answer 1

Answer:

You need to remember the formula for free energy change. After that you need to check the options given, go for trial- error to find out which option gives you most negative ∆G.

WHENEVER ∆G IS NEGATIVE, THE PROCESS IS SPONTANEOUS.

see the formula in the attached photo.

OPTION 3) IS THE ANSWER.

hope you will be able to understand.
