`Au^(3+) + 3^(-) rightarrow Au(s)` `E^(@) = 1.50V` `Cu^(2+) + 2e^(-) rightarrow Cu(s)` `E^(@) = 0.34V` According to the standard

`Au^(3+) + 3^(-) rightarrow Au(s)` `E^(@) = 1.50V`
`Cu^(2+) + 2e^(-) rightarrow Cu(s)` `E^(@) = 0.34V`
According to the standard reduction potentials above, a substance that can oxidize only one of these metals must have an `E^(@)` value:
A. less than 0.34V
B. between 0.34 and 0.80 V
C. between 0.80 and 1.50V
D. greater than 1.50V

`Au^(3+) + 3^(-) rightarrow Au(s)` `E^(@) = 1.50V` `Cu^(2+) + 2e^(-) rightarrow Cu(s)` `E^(@) = 0.34V` According to the standard reduction potentials
