Quantitatively demonstrate that high temperatures and low pressures favor the formation of CO and H₂ in the reformer. Do this by calculating and then plotting the production rates (kmol/kmol of CH₄ fed) of CO and H₂ in the reformer product stream over the temperature range 750°C to 950°C at 1.2, 1.6, and 2.0 MPa. Furthermore, construct plots showing the effect of temperature and pressure on selectivity (defined as kmol CO formed per kmol CO₂ formed) over the same range of conditions.

Assuming that your results support the hypothesis that high temperatures and low pressures favor the formation of CO and H₂, speculate as to why the temperature and pressure are at the values specified in the Process Description (855°C and 1.6 MPa) rather than at a higher temperature and lower pressure.
