Chemical thermodynamics is the study of the relationship between heat and energy in chemical changes and its laws. It explores the transformation of matter and energy, and shows the direction and limit of the reaction.

Chemical thermodynamics is based on the law of thermodynamics. The first law states that energy is conserved, energy can be transferred to each other, and the total amount is constant. The sub-law determines the direction of the spontaneous process, and the principle of entropy increase shows that the isolated system spontaneously increases to a state of disorder.

In chemistry, this theory can determine whether the reaction is spontaneous, measure the equilibrium constant, and know the thermal effect of the reaction. If you calculate the enthalpy change, know the reaction absorbs and releases heat; measure the entropy change and Gibbs free energy change,

All of these are the essence of chemical thermodynamics, which play a great role in the research and practice of chemistry, helping us understand the essence of chemical processes, so as to better control reactions and achieve expected results.
