Question

A reaction has a ΔH0 = + 15.6 kJ and a ΔS0 = + 256.5 J/K. Calculate the minimum temperature for which the reaction becomes product favored.

Answer 1

deltaG=deltaH-T*deltaS
deltaG is free energy, a measure of driving force for a reaction to go. All systems want to minimize free energy, and will go the direction that favors that.

Set delta G=0, this is the transition between which side is favored

Solve for T given deltaH and deltaS

Put all terms in the same units (all kJ or all J, not both)
leave dH=15.6kJ, and make dS=0.2565kJ/K

You'll get T in Kelvins
