The synthesis of methanol from carbon monoxide and hydrogen gas is described by
the following chemical equation:
CO(g) + 2H₂(g) = CH3OH(g)
The equilibrium constant for this reaction at 25 °C is Kc = 2.3 × 104. In this
tutorial, you will use the equilibrium-constant expression to find the concentration of
methanol at equilibrium, given the concentration of the reactants.
