Some N2 and H2 are placed in an empty 5.00 liter container at 500 degree celcius. When equilibrium is established, 3.0mol N2, 2.40mol H2 and 0.565mol of NH3 are present. Evaluate Kc for the reaction at 500 degree celcius.

  1. N2 + 3H2 ==> 2NH3
    At equilibrium,
    (N2) = 3.0/5.00 = ?
    (H2) = 2.40/5.00 = ?
    (NH3) = 0.565/5.00 = ?
    Substitute these equilibrium values into the Kc expression and evaluate Kc.
