Question

Given the standard reduction potentials, which statement is correct?
`{:(Cu^(2)(aq) + 2e^(-) rightarrow Cu(s), E^(@) = 0.34V), (2H^(+)(aq) + 2e^(-) rightarrow H_(2)(g), E^(@)= 0.0V), (Cr^(3+)(aq) + 2e^(-) rightarrow Cr(s),E^(@) = -0.73V):}`
A. Cr(s) will react with acid.
B. Cu(s) will react with acid.
C. `Cu^(2+)(aq)` will react with acid
D. Cu(s) will reacct with `Cr^(3+)(aq)`
