Thermodynamics heat, enthalpy, Gibbs

We know the basic Thermodynamic equations are: $$ dU=-PdV+ TdS + \mu dN$$ $$ dH=dU+d(PV)= TdS+ \mu dN + VdP$$ we typically assume constant Pressure for a reaction carried out in air and neglect the dP term $$dG=dH-d(TS)= \mu dN + SdT+ VdP$$ once again we neglect the dT and dP terms but for heat […]
