Have a little read: ... Science Investigation (Chemistry) - Rate of Reaction Planning: Outline: I will investigate the relationship between the rate of a reaction and the amount of catalyst added to the reaction. I will use hydrogen peroxide and speed pu the decomposition of it by adding manganese(IV), MnO2 as catalyst. Fair test: In order to maintain fair test conditions I will control variables that will affect the rate of reaction. The factors that are able to affect the rate of reaction include: * Temperature * Surface Area * Concentration * Catalyst Since I am investigating the relationship between rate of reaction and catalysts, the other 3 factors will remain constant throughout the experiment. Temperature: At higher temperatures, the faster moving particles have more kinetic energy. This means they are moving quicker and will collide more often and with more energy, causing an increase in the number of effective collisions. Surface Area: If more surface area is available, the number of particles of the solid reactant
