Consider the following reaction:

Question

CO(g)+H2O(g)⇌CO2(g)+H2(g)
Kp=0.0611 at 2000 K
A reaction mixture initially contains a CO partial pressure of 1348torr and a H2O partial pressure of 1780torr at 2000 K.

Calculate the equilibrium partial pressure of CO2.
Calculate the equilibrium partial pressure of H2.

Answer 1

pCO = (1348/760) = approx 1.8 atm but you need to do it more accurately.
pH2O = 1780/760 = approx 2.3 atm.
.........CO(g)+H2O(g)⇌CO2(g)+H2(g)
I.......1.8....2.3.....0......0
C.......-x......-x.....x......x
E......1.8-x...2.3-x...x......x

Substitute the E line into Kp expression and solve for x = pCO2 = pH2.
