Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

A catalyst increases the rate of a reaction but it is not used up in the reaction. If a catalyst is present, the reacting particles can collide more successfully with less energy and so the ...

Only a very small mass of catalyst is needed to increase the rate of a reaction. However, not all reactions have suitable catalysts. Different substances catalyse different reactions.

Start by defining what a catalyst is. Link back to previous topic to remind users what activiation energy is. Insert image of Maxwell-Boltzmann distribution curve wihch include what happens when a ...

Catalysts provide an alternative route for reactions to proceed. Image - energy level profie diagram with and without a catalyst. - based on those seen at this link ...
