Gas constant

Description

The gas constant, R = 8.314462618 J·mol^-1·K^-1, has the SI unit for energy per amount per temperature. R is primarily known from the ideal gas equation, pV = nRT or p = cRT. Therefore, RT is the ratio of pressure p and concentration c.

R = f·F, the electrochemical constant f times the Faraday constant F.

R = k·N_A, the Boltzmann constant k times the Avogadro constant N_A.

Abbreviation: R [J·mol^-1·K^-1]
