Question

An equilibrium mixture contain equal moles (n) of each pC PCI, and cl, f 20 mol of hcl) is added at equilibrium at constant temperature and pressure, volume of the system is double. What is n

Answer 1

Answer:

PCl

5

(g)

⇌ PCl

3

(g)

+Cl

2

(g)

Initial t=0 1 0 0

At equilibrium 1−α α α

Total number of molus =1−α+α+α

=1+α
