1. Suppose the chemical reactions and corresponding redox potentials in a battery are: Li Li* + e Vrp = 3.04 V S + 2e S- a. Vrp = -0.57 V Which material, lithium or sulfur, gets oxidized, and which material gets reduced? (5 points) b. Which material would be the cathode material? (3 points) c. Which would be the anode material? (3 points) d. The cell voltage is the sum of the redox potentials [note that multiplicity is not a factor! This changes the battery capacity, but not the potentials themselves] - what would the voltage of this battery be? Is it positive? Positive voltages will tend to undergo the reaction and generate the needed charge flow, while negative potentials imply an energetically unfavorable reaction. (4 points)
