RT (energy)

RT (energy)

"RT" is the product of the molar gas constant, "R", and the temperature, "T". This product is used in physics as a scaling factor for energy values in macroscopic scale (sometimes it is used as a pseudo-unit of energy), as many processes and phenomena depends not on the energy alone, but on the ratio of energy and RT, i.e. "E/RT". The SI units for "RT" are joules per mole (J/mol).

In microscopic scale, for molecules, "kT" value is used; its dimension is energy or ["M" "L" "T"−2] , expressed in SI units as joules (J)::"kT" = "RT "/"N"A
