when 0.100mole H2S was put into a 10.0-L vessel and heated to 1132C, it gave an equilibrium maixture containing 0.0285 mol H2. @hat are the valuesw of Kc and Kp at this temperature?

  • chemistry -

    What's the reaction? Is it
    ............H2S(g) ==> H2(g) + S(s)
    initial...0.01M.......0....0
    change......-x......2x.....x
    eqil.....0.01-x....2x.....x
    (Note: (H2S) = moles/L = 0.1/10 = 0.01 M

    Kc = (H2)/(H2S)
    (H2) = 0.0285/10 = 0.00285 = 2x
    Kc = (0.00285)^2/(0.01-x)
    Kp = KcRTdelta n
