Manipulating Cathode or Anode Concentration

Postby ShravanPatel2B » Fri Mar 13, 2020 3:23 pm

Can someone explain the effects of manipulating the cathode and anode in the Ln Q portion of the nernst equation?

In the nernst equation: E = Eo -(RT/nF)ln Q
since the anode foes on top and cathode foes on the bottom for Q, as the reaction progresses, the concentration of the left (oxidation) anode as the solid electrode dissolves while the concentration in the right (reduction) cathode decreases as the electrode in that compartment gains mass
