Answer: Octane will be used completely.
Step-by-step explanation:
To calculate the moles :


The balanced chemical reaction will be
According to stoichiometry :
2 moles of octane require = 25 moles of

Thus 0.0202 moles of octane will require=
of

Thus octane is the limiting reagent as it limits the formation of product and
is the excess reagent.
Thus octane will be used completely.
