1. Comment on the likelihood that the following reactions occur by a simple out-sphere electron transfer, simple atom transfer, or a multistep mechanism:

(a) HIO(aq) + I(aq) → I2(aq) + OH(aq)

(b) [Co(phen)3]3+(aq) + [Cr(bipy)3]2+(aq) → [Co(phen)3]2+(aq) + [Cr(bipy)3]3+(aq)

(c) IO3(aq) + 8 I(aq) + 6 H+(aq) → 3 I3(aq) + 3 H2O(l)

2. Complete and balance the following oxidation-reduction reactions.

a) H2O2(aq) → O2(g)  (pH = 0)

b) MnO4(aq) + C2O42–(aq) → CO2(g) + Mn2+(aq)  (pH = 0)

c) MnO4(aq) + CH3CH2OH(aq) → CH3CHO(aq) + MnO2(s)  (pH = 14)
