Chemical Engineering Thermodynamics
Chemical thermodynamics is the 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 this subject is the four "fundamental equations of Gibbs" that can be applied to derive thermodynamic properties using relatively simple math.
Reaction Engineering
Chemical reaction engineering is a specialty in chemical engineering or industrial chemistry dealing with chemical reactors. In the most generic sense, the term relates specifically to catalytic reaction systems where either a homogeneous or heterogeneous catalyst is present in the reactor.
