HEAT OF REACTION AND GIBBS FREE ENERGY

Hi vikram,

How have you deduced that this energy is free?

Spencer.

spencer, GIBBS FREE ENERGY is a scientific defenition of G= H-TS thus Gibbs Free Energy = Enthalpy - Temp*Entropy. This defines the amount of FREE energy in a reaction that is available to use and to be put to work.It is just there in the reaction, it is not made , it is not chemically produced, it conforms.

Wel Dear I know the fundamentals.Iam technologist, Its my First job to study feasibility of reaction at different Temperature.wheather reaction is feasible or not.

for that i require Janaf Table,presentaly I use NIST DATA BASE
