Chapter 11, Problem 106AE

A standard galvanic cell is constructed so that the overallcell reaction is
${\text{2Al}}^{\text{3+}}\text{(}aq\text{)+3M(}s\text{)}\to {\text{3M}}^{\text{2+}}\text{(}aq\text{)+2Al(}s\text{)}$
where M is an unknown metal. If $\Delta G°=-411\text{ kJ}$ forthe overall cell reaction, identify the metal used to constructthe standard cell.
