Answer:
is the limiting reagent
Explanation:

The balanced chemical reaction is :
According to stoichiometry :
1 moles of
require = 2 moles of 
Thus 0.625 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent as it is present more than the required amount.
