Question

Complete and balance the equation.

N2+H2


Open in App
Solution

When nitrogen and hydrogen react together it gives Ammonia

  • The complete reaction is:

N2(g)+H2(g)NH3(g)

  • Here the reaction is not balanced. as the number of reactants and products are not equal. let's balance nitrogen since it is 2 on the reactant side and 1 on the product side.

N2(g)+H2(g)2NH3(g)

  • Now the number of atoms of nitrogen is equal on both sides. let us make the number of atoms of hydrogen equal on both sides since it is 6 on the product side and 2 on the reactant side

N2(g)+3H2(g)2NH3(g)

  • Hydrogen combines with nitrogen in the ratio of 3:1 by volume, in the presence of iron as catalyst and molybdenum as a promoter at a pressure of 200 atm and 4500C giving ammonia

N2(g)Nitrogengas+3H2(g)HydrogengasFe/Mo200atm450°C2NH3(g)Ammonia

This is the balanced chemical equation.
