RT (energy)

RT (energy) - the product of the gas constant R and the temperature T, has the energy dimension / mol. It is very important because chemical processes and many physical phenomena depend on the ratio of energy changes associated with this phenomenon, E, and the average thermal energy, which for 1 mole of molecules is of the order RT (see chemical equilibrium) that is, it depends on the value (E / RT). Physicists and chemists use RT as a specific (temperature-dependent) pseudo-energy unit.

RT is the size used for macroscopic scale processing, when considering microscopic scale, for single atoms and molecules, the size is: kT = RT / (Avogadro constant).

Ex. For 1 mole of molecules in the gas phase, the kinetic energy is expressed by the formula: E k i n = 3 2 R T {\displaystyle E_{kin}={\begin{matrix}{\frac {3}{2}}\end{matrix}}RT}
