14. The ideal chemical reactors are characterized by the following defining properties: a) there is at least a fraction of fluid perfectly mixed within the reactor; b) the fluid flow within the reactor can be described by two models - perfect mixing or plug flow; c) a perfectly mixed reactor has a small gradient of reaction extent, when the chemical process is faster than the mixing capacity; d) the plug flow reactor has axial gradients of property but id perfectly mixed in cross-section; e) the discontinuous reactor is a distributed parameter system, since it has temporal gradients
