Hi, I was wondering if anyone out there knows the reaction orders for the following reaction:

S2O3^2- + 2H+ ==>SO2 + S + H2O

where

R=K[S₂O₃^2-]^a [H⁺ ]^b

I need the values for a and b, the orders of the reaction, also if you know the answer, please provide some support, or a website or so..

so far i have the following answers
a=2, b=0
a=2, b=1
a=1, b=1
a=1, b=0

and this is suppose to be an experiment, but everyone is getting different results, i'm getting

R=K[S₂O₃^2-]² [H⁺ ]⁰

and i would just like to double check

thanks

First, can you state what the order of a reaction is and how you determine it? Then apply that to your problem. Where does that get you?

Looking at a couple of Web sites myself to remind myself about reaction orders I wonder whether you have given enough information for the question to be answered (I suspect you haven't given all the info but I may be wrong) Have you only given part of the question?

Second, is the equation correct (see also point 3 below)? Does acid being added to S₂0₃^2- (thiosulphuric??) to give Sulphur dioxide and sulphur precipitate. It's a new reaction on me - but that doesn't mean it's not correct (sorry, double negative).

Third, can you please use the sub-script and super-script editing options provided on this message forum when writing out a chemical equation? I find it difficult to follow your question without sub- and super-scripts being used.


Thanks
