Chapter 5, Problem 5.7E

The following is a reaction with initial amounts indicated.

$\begin{array}{l}\text{2Al}+{\text{3Cl}}_{\text{2}}\to {\text{2AlCl}}_{\text{3}}\\ \text{5}\text{.0}\text{mol}9.5\text{mol}1.0\text{mol}\end{array}$

(a) Determine $\xi$ if $\text{3}\text{.5}\text{mol}$ of $\text{Al}$ reacts to make products.

(b) Is it possible for $\xi$ to equal $5$ in this case? Why or why not?
