Chemical thermodynamics is sub-discipline of chemistry or study of the interrelation of heat and work with chemical reactions or with physical variation and changes of state within the limitations of the laws of thermodynamics. Chemical thermodynamics study involves not only laboratory dimensions of a range of thermodynamic properties, but also includes the application of mathematical methods to the learning of chemical questions in addition to the spontaneity of processes.

The structure of chemical thermodynamics study is based on the first two laws of thermodynamics. Preliminary from the first and second laws of thermodynamics, four main equations known the "fundamental equations of Gibbs" can be derived easily. From those four, a multitude of equations, concerning the thermodynamic properties of the thermodynamic system can be derived using relatively a very simple mathematics and this outlines the mathematical framework of chemical thermodynamics.

The main objective of chemical thermodynamics is the concern of a criterion for the determination of the feasibility or spontaneity of a known transformation. In this mode, chemical thermodynamics is usually used to predict the energy exchanges that happen in the following processes:

Chemical reactions, Phase changes, the formation of solutions

The following state functions are of principal concern in chemical thermodynamics:

  • Internal energy (U)
  • Entropy (S)
  • Enthalpy (H)
  • Gibbs free energy (G)

Most identities in chemical thermodynamics happen from uses and applications of the first and second laws of thermodynamics, mainly the law of conservation of energy, to these state functions.

The three laws of thermodynamics are given below

  • The energy of the universe is constant.
  • In a spontaneous process, there is always an raise in entropy of the universe
  • The entropy of a ideal crystal at 0 kelvins is zero.
