2. The Relationship of E° cell to HG° and K: HG° = - RT lnK = -nFE° where: F = Faraday constant = charge per mole of H + = (charge on one H + ) x (Avogadro’s Number) = 96,500 C/mol Electrical Energy Indications of Sponteneity: Some Applications: 2. The Lead Storage Battery (see also text pages 733-734). This is a voltaic cell which, like most commercial batteries, does not require a salt

Unformatted text preview: bridge. The RA and OA are solids and thus can be kept physically separate. (a) The relevant reactions, both written as reductions, are shown. Add these to an E chart. Write out the overall equation under the cell figure. PbO 2 + SO 4-2 + 4H + + 2e- PbSO 4 + 2H 2 O, E = 1.68 V PbSO 4 + 2e- Pb + SO 4-2 , E = -0.36 V (b) Determine Ecell . Add figure here . (c) Indicate the signs of the electrodes, the direction of motion of the ions and e-as the cell discharges. Label the cathode and anode . (d) This battery is: Ridiculous ! Marvelous !! Miraculous !!!...
