A reaction misture is made containing an initial SO2CI2l ot 23x102 M.At equilibrium, [C2I 1.3x 10-2M You may want to reference Peges 830-003) Section 15 8 while completing K. . 11.53. 10-2 this problem Submt x Incorrect; Try Agairn Provide Feedback

Explanation / Answer

PART A

        SO2Cl2(g) <-----> SO2(g) + Cl2(g)

initial 0.023 M              -       -

change -0.013             +0.013      +0.013

equil    0.01 M            0.013        0.013

Kc = [SO2][Cl2]/[so2cL2]

    = 0.013*0.013/0.01

    = 0.0169

    = 1.69*10^-2
