The H2O2 slowly decomposed, but when MnO2 was added, the reaction began to speed up in its process. This included bubbling and discoloration of the H2O2, thus proving that catalysts speed up reaction rates. The error that may have taken place at most stations is that the amount of substance added in each reaction was not exactly precise or the person in charge of the timer did not start it in time or started the timer too early...

GCSE Chemistry PLANNING Background Information: During a chemical reaction the reacting particles must collide with each other, however, collision alone does not guarantee that the reaction will start...	1 / 246
Rate of reaction I think that the higher the temperature of the acid rises, the rate of reaction will increase. For example: If I double or triple the reaction, the rate of reaction will also double or triple...	4 / 924
What Effect The Concentration Of Acid Has On The Rate Of Reaction Aim The aim of this experiment is to find out what effect concentration has on a rate of reaction. Prediction I predict that the higher the concentration of the acid, the faster the reaction will take place, this is because when there is a higher concentration, to a certain extent, there is more particles, so the higher the concentration of acid, the more particles there would be, so these particles will have more chance of colliding with each other, which is what causes the reaction...	2 / 515
Rate of Reaction Temperature and use of a Catalyst Introduction The aim of this experiment was to investigate the affect of the use of a catalyst and temperature on the rate of reaction while keeping all the other factors that affect the reaction rate constant...	4 / 890
Rate Of Reaction - Sodium Thiosulphate And Hydrochloric Acid Aim Investigation, to find out how the rate of reaction between Sodium Thiosulphate and Hydrochloric acid is affected by changing the concentration...	10 / 2623
Rates of Reaction Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate...	4 / 915
How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures...	4 / 939
