Question

The balanced chemical equation for the formation of ammonia gas by the reaction between nitrogen gas and hydrogen gas is given. N₂ + 3H₂ → 2NH₃ 

(a) Write the ratio between the number of moles of reactants and products in the correct order.

(b) How many moles of ammonia are formed when 6 moles of N₂ react with 6 moles of H₂?

Answer 1

(a) 1 : 3 : 2. 

(b) Since, one molecule of N₂ and three molecules of H₂ produce two molecules of NH₃. 

When 6 Moles of N₂ and 6 moles of H₂ reacte then only 4 moles of NH₃ will be produced because all 6 moles of H₂ will be utilised and 4 moles of N₂ will be Unreactive.

2 N₂ + 6 H₂ ⇌ 4 NH₃
