Consider the continuous tank reactor shown below. The reaction$-$taking place is:

The reaction is endothermic and has a third order kinetic. Heat is supplied to the reaction mixture by steam, which flows through a coil, immersed in the reactor's content, with a heat transfer area $A.$

Identify the possible control objectives.

Identify the inputs $($Classify them into disturbances and manipulated variables$)$ that effect the operation of the process.

Identify the outputs.

Identify the state variables.

Construct one feedback and one feedforward control configurations that will satisfy the control objective in the presence of disturbances.
