WebNov 13, 2024 · The Nernst equation for this cell is. E = E ° − (0.059 n)log10Q = 0 − 0.29log100.1 = + 0.285V. Note that E ° for a concentration cell is always zero, since this would be the potential of a cell in which the electroactive species are at unit activity in both compartments. E ° for a concentration cell is always zero, WebSo that would be positive .54 volts, so positive .54 plus 1.66, plus positive 1.66 volts. So the standard potential for the cell, so E zero cell is equal to .54 plus 1.66 which is equal to 2.20 volts. All right, now that we've found the standard cell potential, we can calculate the equilibrium constant. hillside church of god miami https://disenosmodulares.com
