Question

Consider the reaction: CO(g)+H2O(g)⇌CO2(g)+H2(g) An equilibrium mixture of this reaction at a certain temperature was found to have [CO]= 0.0233 M , [H2O]= 0.0155 M , [CO2]= 0.190 M , and [H2]= 0.0274 M . Part A What is the value of the equilibrium constant at this temperature?

Answer 1

Answer:

Kc = 14.4

Explanation:

Let's consider the following balanced equation.

CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)

The equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.

What is the value of the equilibrium constant at this temperature?

$Kc=\frac{[CO_{2}].[H_{2}]}{[CO].[H_{2}O]} =\frac{0.190 \times 0.0274 }{0.0233 \times 0.0155} =14.4$
