The limiting reactant in the reaction is the NO molecule.

What is limiting reactant?

The limiting reactant is the reactant that is present in the least amount in the reaction. The rate of reaction depends on the limiting reactant.

Given the reaction; 4NH3 + 6NO --> 5N2 + 6H2O.

Number of moles of NH3 = 43.4 g/17 g/mol = 2.55 moles

Number of moles of NO = 30 g/30 g/mol = 1 mole

Now if 4 moles of NH3 reacts with 6 moles of NO

2.55 moles of NH3 reacts with 2.55 moles * 6 moles/ 4 moles

= 3.8 moles

Hence, the limiting reactant in this reaction is NO.
