The carbon monoxide hydrogenation reaction to produce methanol is carried out in a continuous tubular reactor that operates in a steady state at 400 K and 8 bar, whose length is such that the effluent is in chemical equilibrium. The reaction proceeds according to the following chemical equation:

CO(g) +2H_2(g) CH₃OH (g)

The feed stream feed contains 20 mol% CO, 40 mol% H and 40 mol% N (fed as inert gas). The thermochemical formation data at
