I am investigating the iodine clock reaction using hydrogen peroxide, potassium iodide, sodium thiosulphate and sulphuric acid. Can you give me an idea as to what overall order of the reaction should be? And with respect to each component?
Igloo says
As far as I know the reaction is first order with respect to hydrogen peroxide, first order with respect to iodide ions, and zero order with respect to hydrogen ions. This makes the reaction second order overall.
Rate = k[H2O2][I-]
Risk assessment

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.
