<u>Answer:</u> The excess reactant for the given reaction is
<u>Explanation:</u>
Limiting reagent is defined as the reagent which is present in less amount and it limits the formation of products.
Excess reagent is defined as the reagent which is present in large amount.
For the given chemical reaction:
We are given:
Moles of calcium nitrate = 3.4 mol
Moles of lithium phosphate = 2.4 mol
By stoichiometry of the reaction:
3 moles of calcium nitrate reacts with 2 moles of lithium phosphate
So, 3.4 moles of calcium nitrate will react with = of lithium phosphate
As, the given amount of lithium phosphate is more than the required amount. So, it is considered as an excess reagent.
Thus, calcium nitrate is considered as the limiting reagent because it limits the formation of products.
Hence, the excess reactant for the given reaction is
