The reaction below is exothermic and has a negative entropy change. It is spontaneous under standard conditions. What can be said about its standard Gibbs free energy change, AG*rxn? (Assume the standard temperature and pressure of 298 K and 1 atm.) 2 H₂ (g) + O2 (g) → 2 H₂O (0) AG'rxn is negative. Nothing can be said about AG rxn AG'rxn is undefined. AG*rxn is positive. AG rxn is zero.
