- The equilibrium constant for the reaction below is 0.18 at 25oC.
PCl3(g) + Cl2(g)PCl5(g)
The following concentrations were measured from the reaction vessel: (4 marks)
[PCl3(g)] = 0.0420
[Cl2(g)] = 0.0240
[PCl5(g)] = 0.00500
- Is this system in equilibrium? Explain.
- If not, in which direction will the system shift?
- Write the Solubility Product Constant (Ksp) expression for the following solution at 275oC.(2 marks)
