Using standard reduction potentials, calculate the standard E¡Æcell, emf, for each of the following reactions. State if each reaction is spontaneous or nonspontaneous. (Use the below reactions AS WRITTEN, DO NOT REARRANGE ANY REACTIONS.) You must show the two half-reactions and balance the gain and loss of electrons.

a. H2(g) + I2(s) -> 2H^1+(aq) + 2I^1-(aq)

b. Ni^2+(aq) + 2Ce^5+(aq) -> Ni¡Æ(s) + 2Ce^4+(aq)

c. 4Ce^3+(aq) -> Ce¡Æ(s) + 3Ce^4+(aq) (Acid solution)

d. 2Al^3+(aq) + 3Cd(s) -> 2Al(s) + 3Cd^2+(aq)
