#Chemical Engineering #Chemical #Thermodynamics

Study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. The backbone of chemical engineering thermodynamics is the four "fundamental equations of Gibbs," which can be applied to derive thermodynamic properties using relatively simple math.
