The traditional thermodynamic equation based on heat flow balance without reflecting the variation characteristics of reaction process. New thermodynamics energy conservation is established involving multiple complex factors with process, including species, matter mass and capacity. DSC/DTA acquired from differential equation. new reflects dynamic Kirchhoff's law expresses capacity integral term which both decided by progression. Two kinds modes CaCO3 reactions are carried out to verify theoretical calculations well in accord experimental data, validates accuracy reliability Reaction process; Thermodynamic equation; DSC/DTA; Thermal
