How to find feasibilty with standard reduction potentials?

Question

With these reduction potentials:
SO2 + 2H2O --> SO4- + 4H+ + 2e- E/v = -0.17
VO2(sub)+ + 4H+ + e- --> VO2(sup)+ + H2O E/v = +1.00
VO2(sup)+ + 2H+ + e- --> V3+ + H2O E/v = +0.34

What will happen if SO2(g) is bubbled into VO2(sub)+(aq) ?

Answer 1

You have to determine the net E' for the rxn.
Enet=E(reduction)-E(oxidation)
if the answere is + it is feasable if it is - it is not
Enet=(+1.00v)-(-0.17)
=+1.17
therefore this is a feasable rxn

Answer 2

The forward reaction is accelerated.
