4. Does the rate depend on linear velocity? With external diffusion,
the rate at constant space velocity increases with linear velocity, at about
1/2 order. Velocity independence is a good indication of the absence of
external diffusion effects.
5. What does the observed rate indicate? Take any conversion data,
laboratory or plant, whichever are available. Make calculations as shown
in the example. If more precision is needed, use any of the criteria given
in standard references. (33)
