Answer: is considered as the limiting reagent for this reaction.
Explanation:
Limiting reagent is the reagent which limits the formation of the product.
Excess reagent is the reagent which is present in excess in a chemical reaction.
For the combustion of acetylene, the reaction follows:
By Stoichiometry,
5 moles of oxygen gas reacts with 2 moles of acetylene.
So, 81 moles of oxygen gas will react with = = 32.4 moles of acetylene.
As, the required amount of acetylene is less than the given amount. So, it is considered as an excess reagent and oxygen gas is the limiting reagent.
