You are asked to investigate the effect of temperature on the rate of decomposition of aqueous hydrogen peroxide.
Aqueous hydrogen peroxide decomposes to make oxygen gas.
hydrogen peroxide → water + oxygen
The reaction is very slow unless a catalyst is added to the hydrogen peroxide. Manganese(IV) oxide is a catalyst for this reaction.
Plan an investigation to find how the temperature of the aqueous hydrogen peroxide affects the rate of the catalysed reaction. Your answer should include an explanation of how your results will tell you how the rate of reaction has changed.
You are provided with aqueous hydrogen peroxide, manganese(IV) oxide and common laboratory apparatus.
