Question

10. A student carried out the reaction shown by reacting 10.0g P4 with excess Cl2 and obtained 35.0g of PCl3. P4 + 6Cl2---> 4PCl3

a. What is the theoretical yield of PCl3?
b. Calculate the % yield of PCl3

Answer 1

10.0 g P4 = 0.0807 moles

That should produce 0.3229 moles of PCl3 = 137.33 g
that makes just 35/137.33 = 25% yield
