Of importance to electroanalytical chemistry are the values of the Boltzmann constant, the elementary charge, and the Avogadro constant. These are given in the table below, with calculated values of the Faraday constant (\\(F = e·N_{\\rm{A}}\\)) and gas constant (\\(R = k\\cdot\\!N_{\\rm{A}}\\)).","sources":["PAC, 2020, 92, 641.
