#H_2#

Explanation:

The reaction equation says that three moles of #H_2# and one mole of #N_2# are required to make two moles of ammonia. Since more #H_2# is used up per mole #NH_3# produced, the hydrogen will be used up first.

#H_2 ."is". the. "limiting". "reactant"#

Explanation:

A quick way to determine limiting reagent (or, reactant) is to convert all data dimensions to moles and divide each by the respective coefficient in the balanced Equation. The smaller number will be the limiting reactant.
