(AAAAA)The standard reduction potentials of lithium metal and chlorine gas are as follows: (for Li, reduction potential is -3.04, for Cl it is 1.36)
In a galvanic cell, the two half-reactions combine to 2Li{+](s) + Cl{-}2(g) --> 2Li{+}Cl{-}(aq)
Calculate the cell potential of this reaction under standard reaction conditions. Express your answer with the appropriate units.(I tried -4.4, -1.68, +1.68 volts. But all of these three are wrong.)
(BBBBB)Calculate the free energy of the reaction.
(CCCCC)What can be said about the spontaneity of this reaction?

4.4volts
free energy=-nF*4.4 F is farady constant, n is two moles
is it spontaneous? Is the Gibbs free energy negative?
