1st Question: Consider the following reaction:

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

kc=2.99*10^-7 at 227Celsius.

If a reaction mixture initially contains 0.159M SO2Cl2 , what is the equilibrium concentration of Cl2 at 227 Celsius ?

Question 2: CO(g) + H2O(g) <----> CO2(g) + H2(g)

A reaction mixture initially contains a CO partial pressure of 1342 torr and a H2O partial pressure of 1778torr at 2000K.

Part A: Calculate the equilibrium partial pressure of CO2 .

Part B: Calculate the equilibrium partial pressure of H2.

I do not know how to do this. I am stuck in the quadratic formula, and i am getting a wrong answer, is some can please tell me how to do it. I will really appreciate it

Thank You so much
