Consider the following reaction:
CO(g)+H2O(g)⇌CO2(g)+H2(g)
Kp=0.0611 at 2000 K
A reaction mixture initially contains a CO partial pressure of 1336 torr and a H2O partial pressure of 1764 torr at 2000 K.

Part A
Calculate the equilibrium partial pressure of CO2.

Part B
Calculate the equilibrium partial pressure of H2.

Solutions

Expert Solution

                          CO(g)    +     H2O(g)   ⇌CO2(g)    +    H2(g)

I                       1336               1764           0                     0

C                       -x                     -x             +x                    +x

E                    1336-x            1764-x           +x                   +x

         Kp   = PCO2 * PH2/[PCO *PH2O

        0.0611 = x*x/(1336-x)(1764-x)

        0.0611*(1336-x)(1764-x)   = x^2

                x = 303.53

      PCO2 = x   = 303.53torr

     PH2   = x    = 303.53 torr
