well x^2 - y^2 = a^2 is x= +/- a/rt2 where a^2/2 = c^2 so for the xy = c^2 its just that rotated 45, therefore x + y = +/- a

so did you just assume 100 in those subjects went to 100, or did someone you know get 100 raw ? D:

Err what I got from this exam is that you there was an increase in data analysis type questions which is maybe to combat mofos who just memorise excel.

Yes but isn't part of le chateliers principle that catalyst do not favour equilibrium one way or the other

What is the end all definition of a catalyst? Conc acids are used to speed up the rate of reaction/lower activation energy/increase rate of reaction both ways in equilibrium, but surely if conc acids are dehydrating agents then they are actually getting involved in the equlibrium, e.g. favouring...
