I have just joined and I am posting a new thread. Sorry if this is bad manners! Can anyone point me in the right direction where I can get a curly arrow diagram of the following reaction:- 2H2SO4 = SO3 + H3O+ + HSO4- All help is appreciated here!!

Hi to all, I am very slowly going through an OU course in Chemistry and 'er no I will not be posting my tutor's questions directly on this website!!!! I am of course new here and very much a greenhorn when it comes to chemistry so I am not likely to be much help!! ...But I will certainly be needing it!!!!
