Equilibrium data for the synthesis of MeOH are best expressed assuming that the change occurs in 2 stages CO+H2=CH2O and CH2O+H2=MeOH. The first equation is slow, while the second is almost instantaneous, so that analysis shows only a minimum of CH2O present at any time. The equation of the reaction curve is expressed as
where a=partial pressure of CO, x=amount of CO converted in time t, and thus equals the amount of CH2O formed. The heat of reaction is calculated as 21,000 cal.
