Does anyone have any ideas of what areas will come up in this F331 exam
I have revised it all and such but if anyone knows if there are any likely things to come up which didnt in Jan it would be sueful to look over them more so
But i've done every single past paper, read my revision guide, read the bloody story lines and if its still hard im gonna guage my eyes out literally..

As long as you are comfortable with EVERY point on the specification you will be absolutely fine
so freaked out about this exam. can anyone explain to me what a zeolite is? i never quite understood
It acts like a sieve for isomers. it has holes/pores in it which allow straight chain isomers through, but traps branched chain isomers. and this separates the isomers

Also worth noting that some questions simply want the answer 'Large surface area' when asking about catalysis and zeolites.
which kind of question? i know when it asks what is a catalytic poison, you get one mark for saying it reduces the catalysts surface area
I think by saying that it has a larger surface area this is one of the reasons why it speeds up a reaction. So any question about how catalysts will speed up a reaction. I think

I think it was along the line of 'what properties make a zeolite a good catalyst?' as opposed to 'what allows a zeolite to differentiate between straight and branched chains?' or somthing along those lines.

Do you think we need to know about the squeaky pop test for hydrogen gas?
