← ScienceWhich outcome reduces methanol yield in a synthesis reactor?
A)Increasing reactor operating setpoint temperature✓
B)Decreasing catalyst particle surface area
C)Using a more active catalyst loading
D)Constricting the reactant mass flow rates
💡 Explanation
Elevated temperature shifts the methanol synthesis equilibrium backward due to Le Chatelier's principle. This reduces methanol yield because the exothermic reaction is less favored, therefore methanol production diminishes rather than increases as temperatures rise beyond optimal values.
