The Kp for the production of phosgene is 18.0. If one mole each of CO and Cl2 are
mixed at the total pressure of 1 atm, what will be the partial pressure (in atm) of COCl2
after equilibrium is reached, CO(g) + Cl2(g)-->COCl2(g)

    mols CO = 1
    mols Cl2 = 1
    total mols = 2
    XCO = 1/2 = 0.5
    XCl2 = 1/2 = 0.5
    pCO = XCO * Ptotal = 0.5 x 1 = 0.5 atm
    pCl2 = XCl2 * Ptotal = 0.5 x 1 = 0.5 atm

    .......CO(g) + Cl2(g)-->COCl2(g)
    I......0.5.....0.5........0
    C.......-x......-x........x
    E....0.5-x.....0.5-x......x

    Substitute the E line into Kp expression and solve for x = pCOCl2
