Consider the reaction.
\(\mathrm{CO}(g)+2 \mathrm{H}_{2}(g) \rightleftharpoons \mathrm{CH}_{3} \mathrm{OH}(g)\)
An equilibrium mixture of this reaction at a certain temperature has \([\mathrm{CO}]=0.105 \mathrm{M},\left[\mathrm{H}_{2}\right]=0.114\mathrm{M}\), and \(\left[\mathrm{CH}_{3} \mathrm{OH}\right]=0.185 \mathrm{M}\). What is the value of the equilibrium constant at this temperature?

ANSWER: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.
