Question
Answer the following
You had phosphorus pentachloride to a flask and
heat it to 250°C until the decomposition reaction
reaches equilibrium.
PCI5g PCI3(g)
+ Cl2(3)
The partial pressure at equilibrium of each gas is
measured:
PPCI5 = 0.0 atm
PPC13 = 0.32 atm
PC12 = 0.25 atm
What is the Kc of this reaction?
