Question

In the reaction 2A₂ + 3B₂ ---> 2A₂B₃
Identify the limiting reagent
2 mol A + 3 mol B
1mol A + 2 mol B
100 atoms A + 100 atoms B

Solution

2 A₂ + 3 B₂ â†’ 2 A₂B_3.
2 moles of A₂ will react with 3 moles of B₂.
1 mole of A₂ will react with 1.5 moles of B₂.
2 mole of B₂will react with (2x2)/3 = 1.33 mole of A₂.
Thus in second case A₂. will be the limiting reagent.
4 mole atoms of A will react with 6 mole atoms of B.
100 mole atoms of A will react with (6x100)/4 = 150 mole atoms of B.
In third case B is the limiting reagent.
