If 6 mol of H, react, how many moles of ammonia will be produced?

Moles of Ammonia produced : 4 moles

Given

6 mol of H₂

Required

moles of Ammonia

Solution

Reaction

N₂ + 3H₂ → 2NH₃

In chemical equations, the reaction coefficient shows the mole ratio of the reacting compound (reactants and products)

From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol NH₃ :

= 2/3 x moles H₂

= 2/3 x 6

= 4 moles
