Explanation / Answer

N2   + 3H2 -------------> 2NH3
3 moles of H2 react with 1 mole of N2
7 moles of H2 react with = 7*1/3 = 2.33moles of N2 is required.
      N2 is limiting reactant
1 mole of N2 react with H2 to gives 2 mole of NH3
2 mole of N2 react with H2 to gives = 2*2/1 = 4 moles of NH3
1mole of N2 react with 3 moles of H2
2 moles of N2 react with = 2*3/1 = 6 moles of H2
    H2 is excess reactant
no of moles of excess = 7-6 = 1 mole
