Is that 5.0 L flask?
(H2) = mols/L = approx 0.15
(CO2) = 0.8/5 = about 0.15 but you need a more accurate answer for both.
..........H2 + CO2 ==> H2O + CO
I.......0.15..0.15......0.....0
C........-x....-x.......x.....x
E.....0.15-x..0.15-x....x.....x
Substitute the E line into Kc expression and solve for x and evaluate CO2 and H2. Note that this looks like a bit of a problem with a quadratic BUT you can take the square root of both sides and avoid that. Take the easy way.
the equilibrium constant Kc for the reaction H2 + Co2 to H2O + CO is 4.2 t 1650°C initially .80 mol of H2 and 0.8 mol Co2 are injected into a 5.0 flask. Calculate the concentration of each species at equilibrium
