question 38

Multiple Choice

Consider the following standard reduction potentials. $$\begin{array} { | l | c | } \hline { \text { Reduction Half-Reaction } } & \mathbf { E } ^ { 0 } \text { (volts) } \\\hline \mathrm { Cr } ^ { 3 + } ( a q ) + 3 \mathrm { e } ^ { - } \longrightarrow \mathrm { Cr } ( s ) & - 0.74 \\\hline \mathrm { Cd } ^ { 2 + } ( a q ) + 2 \mathrm { e } ^ { - } \longrightarrow \mathrm { Cd } ( s ) & - 0.40 \\\hline \mathrm { Ni } ^ { 2 + } ( a q ) + 2 \mathrm { e } ^ { - } \longrightarrow \mathrm { Ni } ( s ) & - 0.23 \\\hline\end{array}$$ Which reaction A-D will proceed spontaneously as written from left to right?

• A) 2Cr³⁺(aq) + 3Cd(s) \(\longrightarrow\)2Cr(s) + 3Cd²⁺(aq)
