Reducing Agents and Standard Reduction Potentials

1) The strongest reducing agent from those listed is: Use your book.

a. Fe+3
b. Fe+2
c. Al+3
d. Al

After looking at the chart of reduction potentials in my book, is it
Al?

2) Select the reagent that will transform Fe+3 to Fe+2.
a. H2
b. O2
c. Br-
d. H+

Well, this is asking for the reducing reagent of Fe (3+), so is the answer H+ since reducing agents reduce oxzidizing agents above it?

Thanks.

I don't have a chart with me, but I think the answer for the first one would be the one with the lowest standard reduction potential. The answer to the second one would be the one that has a lower reduction potential than Fe3+.

Looking at the second one again, would H2 actually reduce Fe (3+) rather than H+, which is actually an oxidizing agent?
