Question

For the reduction of $NO_3^-$ ion in an aqueous solution, E° is + 0.96V. Values of E° for some metal ions are given below$V^{2+} (aq) + 2e^- \rightarrow V$ E° = – 1.19 V$Fe^{3+} (aq) + 3e^- \rightarrow Fe$ E° = – 0.04 V$Au^{3+} (aq) + 3e^- \rightarrow Au$ E° = + 1.40 V$Hg^{2+} (aq) + 2e^- \rightarrow Hg$ E° = + 0.86 VThe pair(s) of metals that is(are) oxidized by $NO_3^-$ in aqueous solution is(are) (a) V and Hg (b) Hg and Fe(c) Fe and Au (d) Fe and V
