Explanation / Answer

CO(g) + Cl2(g) -----------> CoCl2(g)
     PCO = 0.7atm
     PCl2 = 1.29atm
     PCOCl2 = 0.17atm
        Kp = PCOCl2/PCO*PCl2
            = 0.17/0.7*1.29   = 0.19
part-B
               H2(g)   + I2(g) -----------> 2HI(g)
     I   3.35    2.25                  0
     C   -0.03       -0.03               2*0.03
     E      3.32    2.22               0.06
    
        [H2] = 3.32M
        [I2]   = 2.22M
        [HI] = 0.06M
       
              Kc = [HI]^2/[H2][I2]
                  = (0.06)^2/(3.32)*(2.22)   = 0.000488
