Energy Contribution

[laurence14b2f]

Hello! How do we quantitatively assess the energy contribution from non-thermal processes, such as electrical or chemical work, in systems governed by the first law of thermodynamics? Thank you!!!

The capacity for a reaction to do non-expansive work energy i.e chemical and electrical energy is represented by delta G. Delta G is the maximum non-expansive work energy that a reaction releases. We can see the contribution of the first law of thermodynamics when rearranging the terms ΔH = ΔU + PΔV. This gives the enthalpy term in ΔG = ΔH -TΔS
