Investigating orders of reactions

Does anyone know a list of reactions that can be used to invesitgate the orders of reactions

Apart from the X experiment
The clock experiment
and the volume of gas produced

Is there anymore because we have a planning practical to do and our teacher says its not going to using any of these 3, can anyone think of anymore.

We used the hydrolysis of an ester. Example: CH3COOCH2CH3 + H2O ----> CH3COOH + CH3CH2OH
(Ethyl acetate + Water ----> Acetic acid + ethanol)

Get the reactants mixing in a vessel, take a 10mL sample from it every minute or so (and quench it), then perform a titration to find concentration of acetic acid.

OP

do you still have your notes on that practical perhaps send them to mer, because we are really unprepared, our teacher doesnt give us very many notes.

Tbh, I probably don't anymore I'm afraid. That was a few years ago!

Basically the procedure is just as I outlined, do it a couple of times with different initial concentrations, and the calculations are fairly straightforward. Tabulate your results and you should be able to work out orders.
