Consider the following reaction: 10 KCIO3 + 3 P4 → 3 P4010 + 10 KCI
Given 30 moles of P4 and 86 moles of KCIO3, which would act as the limiting reactant?

is the limiting reactant in the given reaction.

Explanation:

Limiting reagent is defined as the chemical specie which gets totally consumed in the reaction and the formation of product is dependent on this reagent.

We are given:

Moles of = 30 moles

Moles of = 86 moles

The given chemical equation follows:

By Stoichiometry of the reaction:

If 10 moles of reacts with 3 moles of

Then, 86 moles of will react with = of

As, given amount of is more than the required amount. So, it is considered as an excess reagent.

Therefore, is considered as a limiting reactant because it limits the formation of product.
