P4 (s) + 6Cl2 (g) -> 4 PCL3 (l) What is the maximum amount of phosphorus trichloride that can be formed if 10 molecules of P 4 are mixed with 36 molecules of chlorine?

24 molecules of phosphorus trichloride can be formed

Explanation:

Based on the equation:

P4(s) + 6Cl2(g) → 4PCl3

1 mole of P4 reacts with 6 moles of Cl2 to produce 4 moles of PCl3.

When 10 molecules of P4 react, 60 molecules of Chlorine are needed. As there are just 36 molecules, Cl2 is limiting reactant.

If 36 molecules of chlorine are added, molecules of PCl3 produced are:

36 molecules Cl2 * (4 PCl3 / 6 Cl2) =

24 molecules of phosphorus trichloride can be formed
