The synthesis of methanol from carbon monoxide and hydrogen gas is described by the following chemical equation: CO(g)+2H2(g)⇌CH3OH(g)CO(g)+2H2(g)⇌CH3OH(g) The equilibrium constant for this reaction at 25 ∘C∘C is Kc=2.3×104Kc=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. 1. a. Suppose that the molar concentrations for COCO and H2H2 at equilibrium are [CO][CO] = 0.04 MM and [H2][H2] = 0.04 MM. Use the formula you found...
