In Problem 9.79, the synthesis of methanol from carbon monoxide and hydrogen was described. Further analysis, however, reveals that three reactions can take place:
(a) Show that only two of these reactions are independent.
(b) The equilibrium constants for the first and third reactions are
As in Problem 9.79, the feed composition is 5.0 mole% methane, 25.0% CO, 5.0% CO2, and the remainder hydrogen. The temperature and pressure of the equilibrated product stream are 25O°C and 7.5 MPa. Determine the composition (mole fractions) of the product stream and the percentage conversions of CO and H2.
