Question

Are limiting reagents present in all reactions? Explain

Answer 1

Limiting reagents doesn't present in all reactions.

No. not at all

Explanation:

In any chemical reaction, the reactant which is used first is called as limiting reagent. From a mathematical point of view, there always won't be any limiting reagent. But in the molecular perspective, in a reaction, one of the reactant must used up since we can't count the atoms accurately.

Consequently even if there is an ideal stoichiometric ratio by means of moles mathematically, there may not exist a perfect stoichiometric ratio in terms of molecules probably in molecular view point.
