RT (energy)

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 130.235.77.160 (talk) at 09:32, 4 February 2016 (The dimension of kT is ML^2/T^2 and not ML/T^2). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

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 depend 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 L2 T−2], expressed in SI units as joules (J):

kT = RT /NA
