concentration levels. For this experiment we will also be using a catalyst to speed up the production of oxygen gas. The catalyst being used will be iodide ions‚ which will be introduced into the actual reaction through a mixture of potassium iodide‚ KI. Once all the reactions are complete the rate will be found by using the rate law‚ which shows the dependence of the rate of the reaction of both the iodine and the hydrogen peroxide. Procedure For this experiment we had to work in pairs.

Making up Hydrogen Peroxide Volume required 250 cm3 and concentration required 0.1 moldm-3 Given concentration of H2O2 = 1.7 moldm¬-3 Number of moles (n¬¬¬¬¬¬¬¬¬¬¬) = Concentration (moldm-3) x Volume (dm-3) = 0.1 x 0.25 = 0.025 mol Volume (dm-3) = Number of Moles (n) X 1000 Concentration (moldm-3) = (0.025/1.7) x 1000 = 14.7 cm3 Distilled water required: 250 cm3 – 14.7
