Nernst equation

Nernst equation. E = E ? - lnQ E ? = - At 25 o C, the Nernst equation can be simplified further: E = E ? - lnQ Under equilibrium condition: Q = K, and E = 0 so lnK = E ? * v /25.7mV . Concentration Cells.

A Voltaic Cell

A Voltaic Cell. The chemicals in the salt bridge merely complete the circuit and do not take part in the reaction. If the light bulb lights up, the cell reaction is spontaneous and a current flows between the electrodes ? Voltaic Cell. Standard Hydrogen Electrode (SHE).
