Nitrogen and hydrogen can react to form ammonia:
N2(g) + 3 H2(g)→2 NH3(g)
(a) Write ratios showing the relationships between moles of each of the reactants and products in the reaction.
(b) How many molecules of H2 are required to completely react with two molecules of N2?
(c) How many moles of H2 are required to completely react with 2 mol of N2?
(a)One mole of N2 reacts with 3 moles of H2 to give 2 moles of ammonia.The ratio of number of moles of N2:H2:NH3 is 1:3:2
