dG = dH - TdS.
Go through each answer and see if it fits; for example, #1 can't be right because when dG is - the reaction is spontaneous.
#2.
If dH is - and dS is +, then the term TdS is - so dG is always - when this is true and the rxn is spontaneous. So scratch 2.
Etc.
e?
e?
e?
e is not it.
dG = dH - TdS.
If dS is + then the term -TdS will be negative but some dH values (even though they are + values) still can give a - dG value and the reaction will be spontaneous.
so d then
no. c
