Answer:
Step-by-step explanation:
Number of moles = Weight (in grams)/Molecular Wt.
Mol. Wt. of N2- 28
Mol. Wt. of H2- 2
Since, we have 28g of N2 & 12g of H2
Thus,
No. of moles of N2- 28/28 = 1 mole
& No. of moles of H2- 12/2 = 6 moles
Now, from the stoichiometry of the reaction
N2 + 3H2 → 2NH3
We can see that, for 1 mole of N2 we require 3 moles of H2 to produce 2 moles of NH3 and here for 1 mole of N2 we have 6 moles of H2 i.e. we have 3 moles of excess H2 which will be unused. Thus for the given case N2 will be the limiting reagent
