O
Parameter in the expression for the thermionic emission current density J for a metal in terms of the thermodynamic temperature T and work function. +
Part of the electrode polarization arising from a charge-transfer step of the electrode reaction. +
Partial differential quotient of the cross section of a process with respect to the solid angle around a given direction and the energy of a particle scattered in that direction. +
Partition function of a molecule. +
Perceived power of light. +
Permittivity divided by electric constant. +
Physical constant that by definition (after the latest revision of the SI system that was enforsed May 2019) has a known exact numerical value when expressed in SI units. +
Physical constant used to define a unit system. Hence, when expressed in that unit system they have an exact value with no associated uncertainty. +
Physical constants are categorised into "exact" and measured constants.
With "exact" constants, we refer to physical constants that have an exact numerical value after the revision of the SI system that was enforsed May 2019. +
Physical quantities defined within the domain of batteries. +
Physical quantities defined within the domain of electrochemistry. +
Platinized platinum electrode saturated by a stream of pure gaseous hydrogen. +
Porous electrodes consist of porous matrices of a single reactive electronic conductor or a mixture of solids that include essentially non-conducting, reactive materials in addition to electronic conductors. An electrolytic solution fills the void spaces of the porous matrix. At a given time, there may be a large range of reaction rates within the pores. The distribution of these rates will depend on physical structure, conductivity of the matrix and of the electrolyte, and on parameters characterizing the electrode processes themselves. +
Position vector of a particle. +
Potential of a platinum electrode in 1 M acid solution. +
Potential of an electrode when no electric current flows through the cell and all local charge transfer equilibria across phase boundaries that are represented in the cell diagram (except at possible electrolyte-electrolyte junctions) and local chemical equilibria are established. +
Potentiometry in which the potential is measured with time following a change in applied current. +
