Part A: Spontaneity of redox reaction 1. Use the standard electrode potentials to calculate the cell potential and determine whether the reaction is spontaneous or non-spontaneous. Explain your answers. a) Au3+ + 3 Fe2+ → 3 Fe3+ + Au b) Pb + So,2 + H20 → Pb2* + SO,2 + 2 OH- 2. Given the following lab data Sn2* + Ni Spontaneous Ni2+ Fe Spontaneous Cr2+ + Fe Non spontaneous a) Rank the oxidizing agents in decreasing order of strength. b) Rank the reducing agents in decreasing order of strength. c) Will Sn2* react with Cr? Explain? d) Will Fe2* react with Sn? Explain Part B: Faraday's Law Calculate the time required to produce 23.0 g of nickel from the electrolysis of NiCl2tq) by using a current of 15.0 A. Sketch this cell labeling the anode and the cathode and showing the flow of ions.
