Explanation:
As the given chemical reaction equation is as follows.
[tex]2Cl_{2}(g) + 7O_{2}(g) + 130 kcal \rightarrow 2Cl_{2}O_{7}(g)[/tex]
Also, it is given that for 2 moles the energy required is 130 kcal. This means that energy required for 1 mole is calculated as follows.
1 mole = [tex]\frac{130 kcal}{2}[/tex]
= 65 kcal
Hence, energy required for 7 moles will be calculated as follows.
Energy required = [tex]7 \times 65 kcal[/tex]
= 455 kcal
Thus, we can conclude that energy required to produce 7.00 mol [tex]Cl_{2}O_{7}[/tex] on the basis of given reaction is 455 kcal.
