Overall cell potential
WebPrelab Questions: (PL1) For 6 galvanic cell combinations in part 1, write a chemical equation for each cell in a direction that would be spontaneous and the overall cell potential (PL2) For part 2, what is the expected cell potential for that concentration cell? (PL3) Draw a data table you will be filling in during the lab. WebDec 9, 2024 · The overall cell potential (E°) is the difference between the standard reduction potential of the cathode and the standard reduction potential of the anode. E° = E°red, cat - E°red, an = 0.80 V - 0.15 V = 0.65 V Advertisement Advertisement
