Cannon Fire Demonstration

In this National STEM Learning Centre and Network video, Simon Quinnell demonstrates a spectacular and noisy experiment showing the oxidisation of hydrogen peroxide using ethanol and potassium permanganate. An exciting illustration of energy changes, the sound of these substances reacting with each other sounds like cannon fire.

Can this be used to explain catalysts in Unit C2 for rates of reaction?

thank you

It's a great little demo but far better to explain catalysis theory is the decomposition of peroxide with cobalt ions as a catalyst - it shows the reaction getting faster but more importantly demonstrates visually the formation of an intermediate and the reformation of the catalyst in its original form.http://www.nuffieldfoundation.org/practical-chemistry/involvement-cataly...
