For a chemical reaction to happen: There are different ways to determine the rate of a reaction. The method chosen usually depends on the reactants and products involved, and how easy it is to ...

In this topic you will consider the factors affecting the rate of a chemical reaction such as particle size, concentration, pressure, temperature and the use of catalysts. You will seek to explain ...

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 ...

Rate graphs are of two common types: Concentration (y axis) against time (x axis). Rate (y axis) against concentration (x axis). The shape of each graph indicates whether the order of reaction for a ...
