WILL MARK BRAINLIEST!!! Which of the following combinations will result in a reaction that is never spontaneous?
1) positive enthalpy change and positive entropy change
2) positive enthalpy change and negative entropy change
3) negative enthalpy change and positive entropy change
4) negative enthalpy change and negative entropy change

Respuesta :

2. 

G=H-TS
G=(+)-T(-)
G=(+)+(+)

Since G would be positive no matter what the temperature could be, the reaction could never be spontaneous.
