Thermodynamics databases

Thermodynamics databases are collections of data related to the thermodynamic properties of substances, including elements, compounds, and mixtures. These databases are used to store, organize, and provide easy access to thermodynamic data such as: 1. **Phase Equilibria**: Data related to phase changes and equilibria between different states of matter (solid, liquid, gas).

In biochemistry, the table of standard reduction potentials (E°' values) for half-reactions is crucial because it helps to predict the direction of redox reactions in biological systems. The standard reduction potential measures the tendency of a substance to gain electrons (be reduced). Here are some key points regarding its importance: 1. **Electron Transfer**: Many biochemical reactions involve the transfer of electrons, especially in metabolic pathways like cellular respiration and photosynthesis.

Thermodynamic databases for pure substances are comprehensive compilations of thermodynamic properties and data for individual chemical substances. These databases provide essential thermodynamic information that is critical for engineers, scientists, and researchers involved in various fields such as chemical engineering, materials science, thermodynamics, and environmental science. ### Key Features of Thermodynamic Databases: 1. **Properties Catalog**: - **Phase Behavior**: Information on phase changes, including phase diagrams, boiling points, melting points, and critical points.
