for a thermodynamically stable reaction what will be the signs of delta H, deltaS and delta G?

A thermodynamically stable reaction is one where delta G (free energy) is negative, which would indicate a spontaneous reaction (energy state of the reactants is higher than the energy state of the products and reaction will proceed spontaneously without added energy. Thus, this leaves delta H to be - and delta S to be + for delta G to always be negative. Delta H and delta S could also be different signs, but then the sign of G varies on whether it is at a high temperature or low temperature.
