For the reduction of `NO_(3)^(c-)` ion in an aqueous solution, `E^(c-)` is `+0.96V`, the values of `E^(c-)` for some metal ions are given below `:` `i.V^(2+)(aq)+2e^(-)rarr V, " "E^(c-)=-1.19V` `ii. Fe^(3+)(aq)+3e^(-) rarr Fe, " "E^(c-)=-0.04V` `iii. Au^(3+)(aq)+3e^(-) rarr Au, " "E^(c-)=+140V` `iv. Hg^(2+)(aq)+2e^(-) rarr Hg, " "E^(c-)=+0.86V` The pair`(s)` of metals that is `//` are oxidized by `NO_(3)^(c-)` in aqueous solution is `//` areA. V and HgB. Hg and FeC. Fe and AuD. Fe and V |

Answer» Correct Answer - A::B::D Since with `V, Fe` and `H_(2),E^(@)` of cell is positive so `DeltaG^(@)` will be negative. |
