The following reaction was carried out in a 2.25L reaction vessel at 1100 K:

C(s)+H2O(g)⇌CO(g)+H2(g)

If during the course of the reaction, the vessel is found to contain 8.50mol of C, 15.9mol of H2O, 3.00mol of CO, and 6.30mol of H2, what is the reaction quotient Q?

    reaction quotient Qc has the same expression as equilibrium constant Kc ....

    Qc = [CO] [H2] / [H2O]

    solids are not written in Qc expression

    [CO] = no.of moles of CO/volume in litres = 3/2.25 = 1.33

    [H2] = 6.3/2.25 = 2.8

    [H2O] = 15.9/2.25 = 7.067

    so Qc = 1.33 X 2.8 / 7.067 = 0.527
