Question

write the relation between free energy ,enthalpy and entropy

Answer 1

Gibbs free energy combines enthalpy and entropy into a single value. Gibbs free energy is the energy associatedwith a chemical reaction that can do useful work. It equals the enthalpyminus the product of the temperature and entropy of the system. ... If ΔG is positive, then the reaction is non-spontaneous
DeltaG=DeltaH-DeltaT(s)

Answer 2

∆G=∆H-T∆S is the required relation
