Rates of reaction - kinetics (A2)

What effects do metal oxides have on the rate of decomposition of hydrogen peroxide either as inhibitors or catalysts.
Igloo writes ...
Some oxides of transition metal elements, such as manganese(IV) oxide, accelerate the rate of decomposition. That is, they act as positive catalysts. However, oxides of s block metals, such as magnesium oxide, tend not to catalyse the decomposition at all. As far as I know, no metal oxide acts as an inhibitor.
You will find some information on all this in Topic 19 of the Nuffield Chemistry Students’ Book.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
