Hey everybody,

I was just wondering whether it is possible to work out the order of this oxidation reaction:

2Mg+O2 => 2MgO ,knowing only this reaction equation, the oxidation states of each (and a Pilling-Bedworth ratio not
sure if necessary). P-B =0.39 and the concentrations are all unknown, reaction constant k is also unknown.

I've also deduced that it takes one O2- for every Mg2+ ion. Can this be used in the rate equation?

thanks,
jaffrey

In a word, NO. Knowing the reaction and stoichiometry does not provide you with any insight about the rate.
