Introduction
In the reaction of phosphorus pentachloride (PCl5) dissociating into phosphorus trichloride (PCl3) and chlorine gas (Cl2), we can analyze the equilibrium state in a closed container.
Reaction
The balanced chemical equation is:
PCl5 (g) ⇌ PCl3 (g) + Cl2 (g)
Initial Conditions
- One mole of PCl5 is initially present in a 1-liter container.
- The initial concentration of PCl5 = 1 M (since 1 mole in 1 liter).
Equilibrium Concentrations
At equilibrium, it is given that 0.6 moles of chloride (Cl2) are present:
- Since 1 mole of PCl5 produces 1 mole of Cl2, 0.6 moles of Cl2 indicates that 0.6 moles of PCl5 have reacted.
- Therefore, at equilibrium:
- Moles of PCl5 left = 1 - 0.6 = 0.4 moles
- Moles of PCl3 formed = 0.6 moles
- Moles of Cl2 formed = 0.6 moles
Equilibrium Concentrations in Molarity
In a 1-liter container:
- [PCl5] = 0.4 M
- [PCl3] = 0.6 M
- [Cl2] = 0.6 M
Equilibrium Constant (Kc)
The equilibrium constant expression for the reaction is:
Kc = [PCl3][Cl2] / [PCl5]
Substituting the equilibrium concentrations:
Kc = (0.6) * (0.6) / (0.4)
Calculation of Kc
Kc = 0.36 / 0.4 = 0.9
Conclusion
The value of the equilibrium constant (Kc) for the decomposition of PCl5 at the given conditions is 0.9. This indicates the extent of the reaction at equilibrium, illustrating the balance between reactants and products.
