Chemical Equilibrium with individual reactions

  1. Jan 21, 2010 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    Kc = (Kp)/ (RT)delta n

    K_c = (K_a)(K_b)
    (Where a and b are the individual reactions while c is the overall reaction where the coefficients are the same)

    3. The attempt at a solution
    The question prior to this one has individual reactions as well, but those individual reactions add up the overall one (with the exception of the coefficient though, which however just need to raise the result to the appropriate power).

    With this question, I can't seem to balance those 3 individual reactions so that they could math the overall equation as given by the instruction.

    One problem to me is that CH4 and C2H2 have to be on different side, so I thought maybe I could reverse one of the individual reactions (either the 1st or 2nd one) so that the position is correctly matched to the overall reaction. Even after doing that I am unable to reach the equation as the same one. There are other elements that will still remain in the individual reactions while not appear in the overall one.

    Please advice. Thank you very much in advance.
