Conversion of Methanol to Formaldehyde
Consider the production of formaldehyde by gas-phase pyrolysis of methanol  by the reaction . This Demonstration plots the extent of the reaction versus temperature (in kelvin) for user-set values of the pressure . Two methods are compared: (1) the Gibbs free energy minimization technique, shown by the red curve; and (2) the reaction coordinate method, indicated by the blue triangles. Perfect agreement is observed between the two approaches.
