.........PCl5 ==> PCl3 + Cl2
initial...0.123.....0.......0
change...-2p........p.......p
equil...0.123-2p.....p......p
Substitute the equilibrium values into the expression for Kp and solve for p.
Post your work if you get stuck.
The equillibrium constant (Kp) for the interconversion of PCl5 and PCl3 is 0.0121:
PCl5(g) --> PCl3(g) + Cl2(g)
A vessel is charged with PCl5, giving a initial pressure of 0.123 atm. At equillibrium, the partial pressure of PCl3 is _____ atm.
