Three moles of PCl ₅ , three moles of PCl ₃ and two moles of Cl ₂ are taken in a closed vessel. If at equilibrium the vessel has 1.5 moles of PCl ₅ , the number of moles of PCl ₃ present in it is
Options
- A5
- B3
- C6
- D4.5
Correct answer
D. 4.5
Step-by-step solution
At equilibrium 1.5 moles of PCl is converted into 4.5 moles of PCl 3 . Total moles of PCl ₃ at equilibrium is 4.5 .
