Many students opt for the differential method to determine reaction order and rate constant from data generated in the virtual lab.

The method has a few pitfalls, however. In this video, we point out these drawbacks and suggest ways to make the results more reliable.

Flow rate in gas phase reactors can vary due to chemical reactions. To deal with this, some textbooks present a method that assumes flow rate depends linearly on conversion.

A more general treatment is not at all more complicated. Here we show how to easily solve the steady state of a gas phase CSTR with variable flow rate using Excel Solver.

In practice, chemical systems rarely involve just a single reaction. It is therefore important to provide students with tools to cope with multiple parallel and consecutive reactions.

This video demonstrates how the numerical solution of the governing equations for ideal reactors can be made straightforward. Examples are given for the batch reactor, the CSTR and the PFR to clarify the concept.
