Question: a liquid phase reaction a to b takes places in...

A liquid phase reaction A to B takes places in a well-mixed reactor of volume, V. The reactor is initially empty. At time zero a solution of A at Ca0 flows into the reactor at a constant flow rate of Qin. No liquid leaves the reactor until it is full. The reaction rate is second order. Develop a model which you can determine Ca(t) in the reactor while it is filling.
