saAim: To find out what affects the rate of reaction (R of R) of the catalysed decomposition of hydrogen peroxide. Apparatus: Boiling Bath, Burette, Clamp stand, Conical flask with side arm, Electronic balance, Hydrogen peroxide, Lab jack, Manganese (IV) Oxide, Measuring cylinders, Rubber Bung, Rubber tubing, Safety spectacles, Spatula, Stop clock, Weighing Boat Method: 1. 1g of Manganese (IV) oxide will be measured out using an electronic balance. 2. 20cm3 of Hydrogen peroxide solution will be measured out into a measuring cylinder 3. The Apparatus will be set up as shown: 4. The bung will be removed and the manganese (IV) oxide will be placed inside the conical flask with side arm.
