Have I missed something? Was there no exam discussion after the exam yesterday? I can't seem to find any. What did everyone think?

They've changed servers or something since the old one isn;t working. All the posts from the last few days are gone.

Thankyou, thankyou thankyou!!! Looks like I've got 100% according to your answers. So friggen stoked!!!

hey mao,

cheers for the solutions,


for the last question if we put the reaction with Cu2+,

would we lose marks for both this reaction question and the last calculation, or just this reaction. (i.e. would they give us consequential for the last)

i got 630 instead of 315 because of the mix up between 2+ and 1+

I would imagine so. Personally I would give you those marks, but I'm not too sure how VCAA will treat it. (It is likely to be something they discuss at the examiner's meeting, but not sure.)

Delta H question should be -71.7

Hi, thanks for this.
I read the graph question wrong and drew the forward reaction instead of the decomposition reaction. I did the effect of catalyst part right (for my graph). Would I get any marks for this... probably the catalyst one, maybe another? Or none at all? Thanks.

Nice spot. I'll get around to fixing it eventually.
