According to the given reaction:

(i) 1 atom of A will react with molecules of B₂ = 1
300 atoms of A will react with molecules of B₂ = 300
But molecules of B₂ actually available = 200
∴ B₂ is the limiting reactant.

(ii) 1 mol of A reacts with 1 mol of B
∴ 2 mol of A will react with 2 mol of B.
Hence A is the limiting reactant.
