Tags Electrode Emf Potential Standard In summary: Substituting the values in the equation, we get:Ecell = 1.602 V - (8.314 J/mol*K * 298 K)/(2 * 9.6485 * 10^4 C/mol) * ln (1) = 1.6137 VTherefore, the emf of the cell at 298K is 1.6137 V.To calculate the change in Gibbs ...
Hence, the electromotive force or cell potential of a cell is the difference between the electrode potentials of the two electrodes constituting an electrochemical cell. The emf of a cell is expressed in volts. The electrodes of an electrochemical cell are designated as the cathode (negative electr...
