Homework Help: Question on Kp

  1. Mar 25, 2012 #1
    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!

    Perhaps it asks about the ease of the thermal decomposition?

    If I will answer yes or no I will do your homework.

    It isn't a homework question anyway, it is a question from a test i gave a few days ago.
    But i am sure about the answer.
