To calculate the Kp of the reaction equation, we’re going to use Hess’s Law. We’re going to manipulate the two reactions with given Kp values such that when we add them together, we will get the reaction equation with the unknown Kp.

Given reactions:

Unknown Kvalue:      C(s) + H2O(g) ⇌ CO(g) + H2(g)                    Kp = ?

Reaction 1:                  C(s) + O2( g) ⇌ CO2(g)                                    Kp1 = 1.363 x 1069

Reaction 2:                  2H2(g) + O2(g) ⇌ 2H2O(g)                               Kp2 = 1.389 x 1080

Reaction 3:                  2CO(g) + O2(g) ⇌ 2CO2(g)                              Kp3 = 1.363 1069

The reactions shown here can be combined to make the overall reaction C(s) + H2O(g) ⇌ CO(g) + H2(g) by reversing some and/or dividing all the coefficients by a number.
a. C(s) + O2( g) ⇌ CO2(g); K = 1.363 x 1069
b. 2H2(g) + O2(g) ⇌ 2H2O(g); K = 1.389 x 1080
c. 2CO(g) + O2(g) ⇌ 2CO2(g); K = 1.363 1069

Select the correct value for K.
