Gibb’s Free Energy

Recommended Posts

The Gibbs function is a Legendre Transformed of the internal energy function, G=U-TS+PV where the the extensive variables, entropy and volume, are replaced by their corresponding intensive variables, temprerature and pressure, respectively.


Its differential: dG=-S dT + V dP + mu dN


Hope this helps.

Gibbs free energy combines both entropy and enthalpy values in the equation....


[math]G =H-TS[/math]


If the value comes out greater than 0, the reaction is thought to be feasible.

what about deltaS and deltaH, dont those factor in somewhere?


Yea your right, my mistake


it should be.....


[math]\Delta G = \Delta H - T \Delta S[/math] at standard conditions.
