Hydorgen peroxide H2O2 can behave as a reducing agent or an oxidzing agent as shown by the two half reactions below labeled R1 and R2. which of the following is true?

R1: O2(g) + 2H+(aq) + 2e- --> H2O2(aq) E0= 0.68 V

R2: 2H+ (aq) + H2O2(aq) + 2e- --> 2H2O(l) E0= 1.78 V

a) R1 demonstrates that hydrogen peroxide behaves as a reducing agent in basic solutions

b) R2 demonstrates that hydrogen peroxide behaves as a reducing agent in basic solutions

c) R1 demonstrates that hydrogen peroxide behaves as an oxidzing agent in basic solution

d) R2 demosnrtates that hydrogen peroxide behaves as an oxidzing agent in basic solution

dont get this question.....does anyone know how to do this?
