Given the following reaction at equilibrium at 450.0

Solutions

Expert Solution

CaCO3(s) ---------- CaO(s) +CO2(g)

Kp= PCO2                                    {CaCO3 and CaO   pressures are taken as unity because they are solid}

Kp = 0.0165 atm

We know that Kp= Kc (RT)Dn

                            0.0165 = Kc (0.0821 x723)1                        (T= 273 + 450= 723K)

                         Kc   = 0.000278

                                Kc   = 2.78 x10-4 M
