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 2.3 x 10^4. In this tutorial, you will use the Kc equilibrium-constant expression to find the concentration of methanol at equilibrium, given the concentration of the reactants.
