Question: how many molecules of nh3 are produced?
Answer: Make the calculations: n(N2)reacted = 1/3*n(H2) = 3 molecules n(NH3)produced = 2/3*n(H2) = 6 molecules The number of unreacted molecules of N2 is 4 – 3 = 1 molecule. Hydrogen is the limiting reactant, so no hydrogen molecules remain unreacted.
