Consider the reaction.
An equilibrium mixture of this reaction at a certain temperature has [CO] = 0.105 M, [H2] = 0.114 M, and [CH3OH] = 0.185 M. What is the value of the equilibrium constant at this temperature?
Solution: Here, we are going to find the value of the equilibrium constant for the given reaction at the given temperature.
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.
For the reaction, CO(g) + 2H2(g) ⇄ CH3OH(g)
