2. A certain reaction measured at 298 K has AH° = +8.7 kJ and AS° = +22.5 J/mol.K. Calculate the value of AG°, and tell if this reaction spontaneous at 298 K? if the reaction is not spontaneous at 298 K, is there a temperature at which the reaction becomes spontaneous? (yes or no). If yes, at what temperature (in K) does it become spontaneous.
