pls help with both

Some COCl2 is placed in a seaied flask and heated to 739K. When equilibrium is reached, the flask is found to contain cocl2(3.16102M),CO(4.18102 M), and Cl2(4.70102M). What is the value of the equalibrium constant for this reaction at 739K ? cocl2(9)a2(9)+Cl2(9)K= The equilitrium constant, Kc, for the following reaction is 1.80102 at 698K. 2HX(g)=H2()+I2() If an equilbrium mixture of the three gases in a 16.4L container at 698K contains 0.272 mol of HI(9) and 0.378 mol of H2, the equibrium concentrotion of I2 is M
