Write the cell notation for an electrochemical cell consisting of an anode where \( \mathrm{Cr} \) (s) is oxidized to \( \mathrm{Cr}^{3+} \) (aq) and a cathode where \( \mathrm{Cu}^{2+}(\mathrm{aq}) \) is reduced to \( \mathrm{Cu} \) (s). Assume all aqueous solutions have a concentration of \( 1 \mathrm{~mol} / \mathrm{L} \). Use the standard reduction potentials located in the 'Tables' linked above to calculate the standard free energy change in \( k] \) for the reaction: \[ 3 \mathrm{Cr}^{3+}(\mathrm{aq})+\mathrm{Cr}(\mathrm{s}) \rightarrow 3 \mathrm{Cr}^{2+}(\mathrm{aq})+\mathrm{Cr}^{3+}(\mathrm{aq}) \]
