Standard reduction potentials $\left( E ^ { \circ \prime } \right)$ and standard free energy change $\left( \Delta G ^ { \circ \prime } \right)$ are related by the
equation $\Delta G ^ { \circ \prime } = - n F E ^ { \circ \prime }$ , where F is the Faraday’s constant and n is the number of electrons
transferred from donor to acceptor. $\Delta G ^ { \circ }$ has units of kJ/mol. Which of the following redox pairs
will have the highest $\Delta G ^ { \circ ' }$ value?

(1) $\mathrm { NO } + 2 \mathrm { H } ^ { + } + 2 \mathrm { e } ^ { - } \rightarrow \mathrm { NO } + \mathrm { H } _ { 2 } \mathrm { O } \quad E ^ { 0' } = + 420 \mathrm { mV }$

(2) $\mathrm { NO } + 8 \mathrm { H } ^ { + } + 6 \mathrm { e } ^ { - } \rightarrow \mathrm { NH } + 2 \mathrm { H } _ { 2 } \mathrm { O } \quad E ^ { \circ \prime } = + 440 \mathrm { mV }$
