The question:
A steel vessel of volume 2.0 dm3 has introduced into it 0.20 mol of SO3, 0.040 mol of SO2 and 0.010 mol of O2.
By calculation of the apparent value of KC show that this mixture is not at equilibrium, and explain in which direction the system will move in order to achieve equilibrium at a temperature of 800K.
The value of KC at this temperature is 1.7 * 10^-6 mol-1 dm3
2SO2(g) + O2 (g) <---> 2SO3
delta H = -196 kJ mol-1
What I have done so far: This is going to look messy
1.7*10^-6 = (SO3)^2/((SO2)^2*(O2))
Do I just substitute the molar values of the components next and see how it compares to the answer in the question?
Also the bit about the temperature doesn't make sense - is it increasing or decreasing?
Thanks for helping, I'm really bad at these type of questions
