Assignment Help Chemistry
Reference no: EM13813723

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

  1. Is this system in equilibrium? Explain.
  2. If not, in which direction will the system shift?

Write the Solubility Product Constant (Ksp) expression for the following solution at 275oC.

MgF2(s)Mg2+(aq) + 2 F-(aq)

Given the solubility of MgF2(s)is 8.4 x 10-7M, calculate the value of Ksp for the reaction shown in question #2 at 275oC.
