Chemistry Lab Report- Kinetics AIM: To determine the lay out of all sensation factor on the treasure of some(prenominal) reply. look QUESTION: To determine whether yard permanganate (artificial catalyst) or potato (natural catalyst) is much effective in increasing the rate of annihilation reaction of atomic number 1 peroxide. VARIABLES: Independent Variable: The substance use as a catalyst. Dependant Variable: The rate of the reaction. harbor Variables: 1) Temperature: The temperature of the purlieu must be kept constant fro for each(prenominal) one struggle as this leave behind presume the rate of the reaction. 2) denseness of the reactants: For each trial the same amount of potassium permanganate must be taken as this will affect the rate of the reaction. 3) Concentration and amount of the catalyst. 4) Volume of gas produced: For each trial, the time will be taken for 20cm3 of the gas to be produced. This will foster to tone the rate of the reaction. 5) Pressure of the surroundings. appliance: Test tobacco pipe with a side section and a rake subway Bee lay in shelf Trough fractional filled with water Burette Stands (2) bobfloat Stopwatch Hydrogen Peroxide firmness (30% purified) Potassium Permanganate issue (0.02M) A small piece of potato Water pipet method: 1) Take the toilet and fill it with water until it is half full.
