Bonus 1. The overall reaction of the Weston cell is: Cd(Hg)amalgam +Hg2SO4(s) 2 Hg(1) + Cd2+(aq) + SO4(aq) The potential of this Weston Cell is 1.0183 V at 20 C. The potential of the Weston cell is temperature dependent and its emf is given by 1.0183 - 0.0000406 (T-20.0) at any other temperature, T. For this Weston cell find A,G°, ArH° and A,S° at which STP is 20°C and 1 atmosphere. (10 pts)
