2A(aq)-> B(aq) +C(aq)
Initial concentration of A and B is 1.00 M, with no C. Kc = 0.200
find equilibrium concentrations

  • Chemistry - ,

    A=0.200


    Can not show work; it will not let me post it.

  • Chemistry - ,

    kc=0.200=C*B/A=C*(1.00 M)/(1.00 M)


    C=0.200 M
    A=1.00 M
    B=1.00M

    Sorry for the typo.

    I don't buy Devron's solution.
    ..........2A ==> B + C
    I........1.00...1.00..0
    C........-2x.....x....x
    E.....1.00-2x..1.00+x..x

    Kc = 0.200 = (B)(C)/(A)^2
    0.200 = )1.00+x)(x)/(1.00-2x)^2
    Solve for x and evaluate 1-2x and 1+x

    Read the problem wrong. The key words were, "initial concentration." I apologize, it was still early.

    Devron, you're absolutely right and I thought that's what you did. I've made the same error but not recently.

  • Chemistry - ,

    You did the easy part... wheres the algebra to find x?
