Problem 54P

Consider the reaction.

An equilibrium mixture of this reaction at a certain temperature has [CO] = 0.0233 M, [H2O] = 0.0115 M, [CO2] = 0.175 M, and [H2] = 0.0274 M. What is the value of the equilibrium constant at this temperature?

Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to find the value of the equilibrium constant for the given reaction at the given temperature.

Step1:

The equilibrium constant for a general reaction,

                        aA + bB ⇄ cC + dD

is expressed as,

                        Kc = [C]c [D]d / [A]a [B]b

Where [A], [B], [C] and [D] are the equilibrium concentrations of the reactants and products.

Step2:

For the reaction,         CO(g) + H2O(g) ⇄ CO2(g) + H2(g)

                        Kc = [CO2] [H2] / [CO] [H2O]

Given,

        [CO2] = 0.175 M

        [CO] = 0.0233 M

        [H2] = 0.0274 M

        [H2O] = 0.0115 M

Substituting the values in the above equation, we get,

                        Kc = (0.175 x 0.0274) / (0.0233 x 0.0115]

                            = 0.004795 / 0.00026795

                            = 17.895

Thus, the value of the equilibrium constant is 17.895.
