1)
Balanced chemical equation is:
N2 + 3 H2 ---> 2 NH3 +
1 mol of N2 reacts with 3 mol of H2
for 0.27 mol of N2, 0.81 mol of H2 is required
But we have 0.856 mol of H2
so, N2 is limiting reagent
we will use N2 in further calculation
According to balanced equation
mol of NH3 formed = (2/1)* moles of N2
= (2/1)*0.27
= 0.54 mol
Answer: 0.540 mol
2)
According to balanced equation
mol of H2 reacted = (3/1)* moles of N2
= (3/1)*0.27
= 0.81 mol
mol of H2 remaining = mol initially present - mol reacted
mol of H2 remaining = 0.856 - 0.81
mol of H2 remaining = 4.6*10^-2 mol
Answer: 0.0460 mol

Answer: 0.0 mol
