It is used in calculating half-cell reactions with varying concentrations, and in determining the concentration of hydrogen ions in a pH meter.
It is used in calculating half-cell reactions with varying concentrations, and in determining the concentration of hydrogen ions in a pH meter. It can be derived by expressing the Gibbs free energy change in terms of the reaction quotient, and then relating the standard free energy change to a standard cell voltage. FTP, name this equation that allows calculation of cell voltage at non-standard conditions.
