Are you assuming that the reaction goes to completion? You don't have a Kp or Kc listed.
What's the limiting reagent? I believe that is CO.
............2CO + O2 ==> 2CO2
I...........10....8........0
C..........-10...-5.......10
E...........0.....3.......10
So you have 13 mols at the end of the reaction. PV = nRT should give you the pressure.
Given: 2CO(g) + O2(g) -> 2C02(g). When 10 mol of CO and 8.0 mol of O2 react in a closed 10L vessel.
a)how many moles of CO, O2, and CO2 are present at the end of the reaction?
b)What will be the total pressure in the flask at 0 degrees C?
