← ScienceWhich consequence results when incomplete mixing occurs in a plug flow reactor?
A)Lower effective reaction rate constant✓
B)Increased catalyst deactivation rate
C)Higher operating pressure requirement
D)Uncontrolled temperature distribution profile
💡 Explanation
Incomplete mixing leads to concentration gradients; thus, the reaction rate is sensitive to varying reactant concentrations. This reduces performance because the effective reaction rate constant is reduced, therefore less product forms, rather than other failures assuming adequate heat transfer design.
