Thermodynamics and Statistical MechanicsHow If a reaction occurs at 293 K that has a change in enthalpy of plus 125 kJ and a change in entropy of plus 35 J K then is the reaction spontaneous If so why If not why not?
Asked by Wiki UserThe spontaneity of a reaction is determined by Gibbs free energy (ΔG = ΔH - TΔS). In this case, the reaction would be spontaneous at 293 K if the calculated ΔG
