The Standard Emf for the Cell Using the Overall Cell $\quad$

The standard emf for the cell using the overall cell reaction below is +2.20 V:
$\quad$$\quad$ 2Al(s) + $3 \mathrm { I } _ { 2 }$ (s) ? $2 \mathrm { AL } ^ { 3 + }$ (aq) + $6 \mathrm { I } ^ { - }$ (aq)
The emf generated by the cell when [ $\mathrm { Al } ^ { 3 + }$ ] = 4.5 × $10 ^ { - 3 }$ mol L^-1 and [ $\mathrm { I } ^ { - }$ ] = 0.15 mol L^-1 is $\text { V. }$
