N_2 + 3H_2 -> 2NH_3. What is the limiting reactant if you start the reaction with 10.0 moles of each reactant?

May 22, 2017

${H}_{2}$

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 $N {H}_{3}$ produced, the hydrogen will be used up first.
