1. The problem statement, all variables and given/known data Which has the max. value of KP- a)MgCO3(s) --> MgO(s)+CO2(g) b)CaCO3(s) --> CaO(s)+CO2(g) c)SrCO3(s) --> SrO(s)+CO2(g) d)BaCO3(s) --> BaO(s)+CO2(g) 2. Relevant equations 3. The attempt at a solution I don't understand how we could determine which has the max. Kp because in all the equations Kp=PCO2. What other factors should i look into? Thanks!
