Jessica Hartley Centre no: 64335 Candidate no: 6107 An experiment investigating the factors which alter the rate of the catalysed decomposition of Hydrogen Peroxide. Aim To investigate one factor that alters the rate of the catalyzed decomposition of Hydrogen Peroxide. Introduction Particles can only react if they collide with enough energy to break existing bonds which will allow for the reaction to take place. This theory is called The Collision Theory. There are four factors affecting the rate of a chemical reaction. These are: Temperature:- Increasing the temperature will cause the particles to move faster, with more energy. They will therefore collide more often and with greater energy. These two things mean there are more successful collisions per second and therefore a faster rate of reaction. Concentration:- Increasing the concentration of a reactant simply means there are more particles which may collide and so react. More collisions means a faster reaction. Surface area:- Using...
