    I am running out of time, so if any one can help give me some formulas or something, that would be great. Thanks.

    1) K of concentration= 0.0198 @ 721 K

    2HI (G) ---> H2(g) + I2(g)

    In a particular experiment, the partial pressures of and at equilibrium are 0.710- and 0.888- atm, respectively. The partial pressure of HI is __________ atm.

    a. 1.98
    b. 0.389
    c. 5.64
    d. 7.87
    e. 0.125


    AND
    In the coal-gasification process, carbon monoxide is converted to carbon dioxide via the following reaction:



    2) In an experiment, 0.35 mol of CO and 0.40 mol of H2O were placed in a 1.00-L reaction vessel. At equilibrium, there were 0.19 mol of CO remaining. Keq at the temperature of the experiment is ___________.

    CO (G) + H20 (G)---->CO2 (G) + H2 (G)
