Motive unit
Description
The motive unit [MU] is the SI unit in which the motive entity (transformant) of a transformation is expressed, which depends on the energy transformation under study and on the chosen format. Fundamental MU for electrochemical transformation are:
- Molecular or particle format, N; MU = x
- Molar format, n; MU = mol
- Electrical format, e; MU = C
For the protonmotive force the motive entity is the proton with charge number z=1. The protonmotive force is expressed in the electrical or molar format with MU J/C=V or J/mol=Jol, respectively. The conjugated flows, I, are expressed in corresponding electrical or molar formats, C/s = A or mol/s, respectively.
The charge number, z, is not involved in the conversion of motive units (see Table below), in contrast to a change not only of units but transition from the entity (e.g., O2 with z=4) to the entity of charge. The ratio of electrons per O2 (zO2=4) is multiplied by the elementary charge (e, coulombs per electron), which yields coulombs per O2 [C∙x-1]. This is multiplied with NA (O2 molecules per mole O2 [x∙mol-1]), thus obtaining for ze∙NA the ratio of coulombs charge per mole O2 [C∙mol-1].
