Question
4. A quantity of 2.40moles of pure SO2Cl2gas was placed in an 8.00 L sealedflask. At 500 K, after
equilibrium isestablished, there are 1.60 moles of the product gasSO2 present. Calculate Kc for the
reaction.SO2Cl2(g) ?? SO2(g) + Cl2 (g)
2.40 mol /8.00 L = .300M initial SO2Cl2 (g) 1.60 mol/ 8.00L = .200 M SO2 (g)at ??
SO2Cl2 (g) ??SO2(g) + Cl2(g)
I .300 0 0
C -x +x +x
E (.300-x) .200 x
So x must = .200 soKc =(.200)2 / .100 =.400
