A concentration cell based on the following half reaction at 309 K Ag+ + e- → Ag SRP = 0.80 V has initial concentrations of 1.37 M Ag+, 0.269 M Ag+, and a potential of 0.04334 V at these conditions. After 9.3 hours, the new potential of the cell is found to be 0.01406 V. What is the concentration of Ag+ at the cathode at this new potential?

Consider the galvanic cell described by (N and M are metals):

N(s)|N2+(aq)||M+(aq)|M(s)

If E^ocathode = 0.182 V and E^oanode = 1.411 V, and [N2+(aq)] = 0.931 M and [M+(aq)] = 0.655 M, what is Ecell, using the Nernst equation? ____ V

(the answer is supposed to be 1.233 but I don't understand how)

A concentration cell based on the following half reaction at 299 K
