Thermochemistry
|
|
Thermochemistry is the application of thermodynamics to chemistry.
Thermochemistry is used to predict the energy exchanges that occur in the following processes:
- chemical reactions
- phase changes such as boiling and melting
- the formation of solutions
Thermochemistry is primarily concerned with the following state functions defined in thermodynamics:
- Internal energy (U)
- Enthalpy (H).
- Entropy (S)
- Gibbs free energy (G)
Most identities in Thermochemistry arise from application of the first law of thermodynamics, the Law of Conservation of Energy, to these state function.
