EmmoTerm
Comment	E^{\circ '} [en] E_{eq} = E^{\circ '} - (RT / (zF)) * \sum_i{\nu_i * ln(c_i/c^{circ})} [en] It is E°′ which is calculated in electrochemical experiments when the concentrations of the various species are known, but their activities are not. Its value depends on the composi- tion of the electrolyte solution. The argument of ln is dimensionless, while the concentration ci is normalized through division by the standard concentration, usually c° = 1 mol dm^{−3} for soluble species. [en]
