Question

Find the relation between Gibbs energy,enthalpy and entropy? Thanku

Answer 1

Well, by definition....

Explanation:

`DeltaG=DeltaH - TDeltaS`

And thus the `"Gibbs' Free energy"` contains an enthalpy term, and an entropy term. And if `DeltaG<"ZERO"` the reaction is spontaneous as written, and therefore thermodynamically favoured.

The standard `"Gibbs' Free energy"` can be related to the thermodynamic equilibrium constant...i.e. `DeltaG^@=-RTlnK_"eq"`...and thus only negative values of `DeltaG^@` give rise to an equilibrium constant GREATER than ONE....
