Define limiting reactant or limiting reagent

Text Solution

Verified by Experts

Limiting reactant Generally, substance takes for chemical reaction are not according to the balanced chemical equation. So, one of the reactant gets consumed completely and the other remains as such. The reactant which gets consumed first is called limiting reactant or limiting reagent. For example, `2H_(2) + O_(2) rarr 2H_(2)O`. Here, `H_(2)` is the limiting reactant as it is consumed completely.
