The reaction of chlorine gas with solid phosphorus (p4)produces solid phosphorus pentachloride. when 16.0 g chlorine reacts with 23.0 g p4, which reactant limits the amount of phosphorus pentachloride produced? which reactant is in excess?

Chlorine gas limit the amount of production of phosphorus pentachloride. And phosphorus was in excessive amount

37.49 grams of phosphorus pentachloride was produced.

Explanation:

Moles of solid phosphorus =

(Molar mass of = 4 × 31 g/mol =124 g/mol)

Moles of chlorine gas =

According to reaction 1 mole of reacts with 10 mol of chlorine gas.Then 0.1854 moles of will react with 1.854 mol of chlorine gas.

This means that chlorine gas is in limiting amount and is in excessive amount.

The production of phosphorus pentachloride will depend upon the amount of chlorine gas.

According to reaction 10 moles of chloroen gas will produce 4 moles of phosphorus pentachloride.

Then 0.4507 moles of chlorine gas will produce:

of phosphorus pentachloride.

Mass of 0.18028 mol of phosphorus pentachloride:

0.18028 mol × 208.5 g/mol=37.49 g

37.49 grams of phosphorus pentachloride was produced.
