Exercise 42. Sketch the galvanic cells based on the following half-reactions. Show the direction of electron flow, show the direction of ion migration through the salt bridge, and identify the cathode and anode. Give the overall balanced equation, and determine ε° for the galvanic cells. Assume that all concentrations are 1.0 M and that all partial pressures are 1.0 atm.
b. Mn 2+ + 2e- → Mn ε° = —1.18 V
Fe 3+ + 3e- → Fe ε ° = —0.036 V
Calculate ΔG° and K at 25°C for the reaction above.
