Problem: Calculate the value of Kp for the equation C(s)+CO2(g) ⇋ 2CO(g) Kp=?given that at a certain temperature C(s)+2H2O(g) ⇋ CO2(g)+2H2(g)                      Kp1=3.39H2(g)+CO2(g) ⇋ H2O(g)+CO(g)                         Kp2=0.625

FREE Expert Solution

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) + CO2(g)  2 CO(g)                                    Kp = ?

Reaction 1:                  C(s) + 2 H2O(g) CO2(g) + 2 H2(g)                     Kp1 = 3.39

Reaction 2:                  H2(g) + CO2(g) H2O(g) + CO(g)                        Kp2 = 0.625
