23.2 Explosions

23.2 Explosions. Thermal explosion: a very rapid reaction arising from a rapid increase of reaction rate with increasing temperature. Chain-branching explosion: occurs when the number of chain centres grows exponentially. An example of both types of explosion is the following reaction

Catalysts

Catalysts . May 6 2011 SCH4U1. Catalysts. A catalyst is a substance which speeds up a reaction without being used up itself. It speeds up the reaction by changing the reaction mechanism to one which requires less activation energy.
