Thus, for a rst-order reaction, the conversion is the same regardless of the extent of
micro-mixing. Segregated ow favours higher-order reactions and micro-mixing favours
fractional order reactions. Thus, higher conversion is achieved for a second-order reaction
in a reactor with segregated ow than in a reactor with complete micro-mixing.
