What factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst?

P LANNING Aim: Our aim is to detect which factors be active the value of the decomposition of henry bleach with a fit(p) the great unwashed of botch pedal. A throttle is a substance, which alters the speed, or rate of a chemical substance reply but is chemically un transfigured at the fetch up of the reply. The dickens factors that we can change are the temperature and the meanness. We chose to vary the submerging of heat content peroxide. The catalyst to speed up the reaction without affecting the solution deal out be atomic number 25 oxide. Prediction: I hazard that the grittyer the concentration of henry peroxide, the faster hydrogen peroxide and manganese oxide decomposes. so the dispirit the concentration of hydrogen peroxide, the move the rate that hydrogen peroxide and manganese oxide decompose. The prediction we pick up just make has been ground on the collision theory-Chemical reactions go by when particles of the reactant collide with plenteous energy (John Holman scallywag 225). If the concentration of the solution is high and so there is to a greater extent chance of the particles colliding. This is because if the concentration increases then so does the human legal action of particles. The more particles there are, the greater the chance of the particles colliding so whence that gives reason to believe that the rate of the reaction increases.

Pre-test During our pre-test less(prenominal)on we needed to permit out the ideal flowerpot of catalyst. We began with 1g of manganese oxide, which we weighed on a top-pan agreement and added it to 100cm of hydrogen peroxide. We apply 100% concentration because we panorama that to crack our catalyst mass was suitable we needed to chink what the more or less reactant experiment would be like. However, 1g of manganese oxide seemed to be too oftentimes as the amount of gas was produced too quickly and we were ineffective to record any...
