Part A: The standard reduction potentials of lithium metal and chlorine gas are as follows:
Reaction Reduction potential
(V)
Li+(aq)+e-→Li(s) -3.04
Cl2(g)+2e-→2Cl-(aq) +1.36
In a galvanic cell, the two half-reactions combine to
2Li(s)+Cl2(g)→2Li+(aq)+2Cl-(aq)
Calculate the cell potential of this reaction under standard reaction conditions.
Part B: Calculate the free energy ΔG° of the reaction.
Part C: What can be said about the spontaneity of this reaction?
