# Problem: An important step in the industrial production of hydrogen is the reaction of carbon monoxide with water (i.e. the water gas shift reaction):CO (g) + H2O (g) ⇋ CO2 (g) + H2 (g)Use the law of mass action to write the equilibrium expression for this reaction.

###### FREE Expert Solution

We are asked to give the equilibrium expression of the given reaction.

The general form of an equilibrium expression is:

$\overline{){{\mathbf{K}}}_{{\mathbf{c}}}{\mathbf{=}}\frac{\mathbf{\left[}\mathbf{products}\mathbf{\right]}}{\mathbf{\left[}\mathbf{reactants}\mathbf{\right]}}}$

Given reaction:

CO (g) + H2O (g) ⇋ CO2 (g) + H2 (g)
(reactants)                                          (products)

When writing equilibrium expressions: ###### Problem Details

An important step in the industrial production of hydrogen is the reaction of carbon monoxide with water (i.e. the water gas shift reaction):

CO (g) + H2O (g) ⇋ CO2 (g) + H2 (g)

Use the law of mass action to write the equilibrium expression for this reaction.
