Question

In the reaction A+ B2 AB2 identify the limiting reagent in the following mixture:

a. 800 mole of A + 200 moleB2

b. 2 mole of A + 3 mole of B2​

Answer 1

Explanation:

(i) 200 molecules of B will react with 200 atoms of A and 100 atoms of A will remain unreacted. Hence, B² is the limiting reagent.

(ii) 2 moles of A will react with 2 moles of B²

and 1 mole of B² will remain unreacted. Thus, A is the limiting reagent.
