    The reaction quatient Q is 0.306

    Explanation:

    Step 1: data given

    Volume = 2.50 L

    Temperature = 1100 K

    Number of moles C = 6.75 moles

    Number of moles H2O = 13.5 moles

    Number of moles CO = 3.10 moles

    Number of moles H2 = 9.00 moles

    Step 2: The balanced equation

    C (s) + H2O (g) ⇌CO (g) + H2 (g)

    Step 3: Calculate the concentration

    Concentration = moles / volume

    [C] = 6.75 moles / 2.5 L

    [C] = 2.7 M

    [H20] = 13.5 moles / 2.5 L

    [H2O] = 5.4 M

    [CO] = 3.10 moles / 2.5 L

    [CO] = 1.24 M

    [H2] = 9.00 moles / 2.5 L

    [H2] = 3.6 M

    Step 4: Calculate Q

    Q = [CO][H2] / [C][H2O]

    Q = (1.24 * 3.6) / (2.7*5.4)

    Q = 0.306

    The reaction quatient Q is 0.306
