Hello! Can someone just guide me? I was calculating thermodynamic functions of some ions and a classmate showed me an equation of enthalpy as function of reduced Gibbs energu and equilibrium constant. [tex]\Delta[/tex]H=T[[tex]\Delta[/tex][tex]\Phi[/tex]-RlnK] where [tex]\Delta[/tex]H is the enthalpy of reaction at 0C, T is the temperature, [tex]\Delta[/tex][tex]\Phi[/tex] is the reduced gibbs energy, R is the ideal gas constant and K is the equilibrium constant. Does anyone know a book or a link where i can refer or just help me to derive that equation?
