Anyone know the answer to this question???
Given the following reaction at equilibrium at 450.0
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
