(a) Limiting reagent

(b) Limiting product

(c) Excessive reagent

(d) Excessive reactant

The question was asked in a national level competition.

I'd like to ask this question from Stoichiometry and Stoichiometric Calculations topic in chapter Chemistry Basic Concepts of Chemistry – Class 11

Answer 1

Right answer is (a) Limiting reagent

Explanation: Though the other substances are excess in amount than the required, each and every reactant needs to be in a fixed ratio to attain the desired product. So, thereby, the reactant that limits the quantity of the product formed is called limiting reagent and this reactant gets consumed first completely.
