NH₃ as the limiting reactant
Given
Reaction
4 NH3 + 5 O2 ⇒ 4 NO + 6 H20
Required
The limiting reactant
Solution
To find the limiting of the reactants, we can use the method by dividing the moles of each reactant by the reaction coefficient. The smallest ratio will be the limiting reactants
the mol ratio of NH₃ : O₂ =
=14/4 : 20/5
= 3.5 : 4
So NH₃ as the limiting reactant
