# Chemical Thermodynamics Assignment Help

Chemical Thermodynamics is the study of the interrelation of work and heat with**chemical reactions**or with physical changes of state within the limits of the laws of

**thermodynamics**. It involves not only the laboratory measurements of various thermodynamic properties, but also the application of mathematical methods for studying the chemical questions and the spontaneity of the processes. On the first two law of thermodynamics, the structure of chemical thermodynamics is based. Four equations called the "fundamental equations of Gibbs" can be derived from the first and second laws of thermodynamics. The chemical thermodynamics is generally used for predicting the energy exchanges that occur in the following processes-

- Phase changes
- The formation of solutions
- Chemical reactions

- Entropy
- Internal energy
- Gibbs free energy
- Enthalpy

- The Universe energy is constant
- There is always an increase in entropy of the universe.
- The entropy of a perfect crystal at 0 Kelvin is zero.

**Gibbs function**- For a bulk system they are the last remaining extensive variables.

**Chemical affinity**- This formulation is mathematically defensible. Though one does not simply remove or add molecules from a system, it is not particularly transparent. In changing a composition, a process is involved. All real processes obey conservation of mass, and the conservation of the numbers of atoms of each kind.
