Hello Student
In the iven reaction one atom of A reacts with one molecule of B so,
(i) 300 atoms of A + 200 molecules of B : B is limiting reagent
(ii) 2 mol A + 3 mol B : A is limiting reagent
(iii) 100 atoms of A + 100 molecules of B : No limiting reagent
(iv) 5 mol A + 2.5 mol B :B is limiting reagent
(v) 2.5 mol A + 5 mol B :A is limiting reagent
