Which of the following criteria indicate that a reaction is SPONTANEOUS? Check all that apply.


a) The change in free energy is positive.

b) The entropy of the universe decreases.

c) The change in free energy is negative.

d) The entropy of the system increases.

e) The entropy of the system decreases.

f) The entropy of the universe increases.

I know C and F are correct but I don't know about the rest. I am confuse with D and E.

    C is correct. I don't understand why F is also true; in fact, isn't F true regardless of the reaction. I understand that the entropy of the universe is increasing and there is no mention of a reaction.

    But do you think that D and E make any reaction spontaneous?
