Methanol production thermodynamic data

A situation often encountered with thermodynamic data is that different sources may present different correlations for a given quantity. In this case study, for example, two different expressions are given for the equilibrium constant for the water-gas shift reaction. Equations 13.9 and 13.12. By what percentages do the conversions of CO and H2 and production of methanol differ if, instead of using Equation 13.12 in Problem 13.15(a), Equation 13.9 is used. Provide at least two reasons for the variations in the two equations for the water-gas shift equilibrium constant. 

DMF as a useful polar solvent is produced industrially on a large technical scale (250000 tons/year) by carbonylation of dimethylamine in the presence of methanol [59]. Using Raney nickel as catalyst, the synthesis of DMF from dimethyl-amine, CO2, and hydrogen was first discovered by Farlow and Adkins [60]. The formation of DMF from dimethylamine, H2, and CO2 is thermodynamically favorable under standard conditions thermodynamic data are given for aqueous reactants and liquid products in eq. (6) [61]. The enthalpy of DMF production (Aff = -56.5 kJ mor, AG° = -0.75 kJ mol, = -119 kJ rnor K- ) is more... 

The data with propylene and methanol showed that once C3 and higher carbon number alkenes approach a significant molar concentration, the methanol reacts predominantly by addition of Cj species to the Cj alkenes. A rapid series of oligomerization/cracking reactions serves to redistribute the initial products toward a thermodynamic equilibrium and a statistical distribution of the added isotope.
