A CSTR is being used to carry out a certain reaction isothermally in the liquid phase. It is observed that the conversion in the CSTR is actually higher than that which was predicted from the design equations. It is also determined that the CSTR is not very well-mixed. Could this explain the observation of high conversion?

The high conversion in a CSTR with not very well mixing occurs mostly if the reactor is micro reactor.

From Literature, mixing due to diffusion depends on concentration or temperature gradients. This is commonly represented in micro reactors.

Also, the residence time distribution (RTD) Analysis provides information on how long the various components of fluid have been in the reactor which leads to more conversion in some cases of fluid reaction.
