For all positive reaction orders for a particular duty,

Density variation during reaction affects design

Mixed reactor is always larger than the plug-flow reactor

Ratio of the volume of the mixed reactor to that of the plug-flow reactor decreases with order

Reactor size is independent of the type of flow
