Catalytic: few atm, 500 deg C Thermal (steam): 70 atm, 700-1000 deg C

I have another question guys, do we have to know general branches of chemistry and what chemists do in those fields?

We should do more questions relating to dotpoints where students often forego e.g. - outline the role of a chemist employed in a named industry or enterprise, identifying the branch of chemistry undertaken by the chemist and explaining a chemical principle that the chemist uses - identify the...

Renewable: Fermentation of glucose from crops Non-renewable: Hydration of ethylene obtained from petroleum fractions or cracking Quick question back @ you, how come you specifically mentioned catalytic cracking? :S Isn't ethylene also from thermal

Really? I would have gone with B. Calculated n: p ratio comes out to something like 1.6:1 which is not a low ratio :S Edit: actually idk anymore I wouldn't have gone with any of them lol -_-

He aint gonna get a state rank with that last denominator (x-1)^x !!! : P GW though

Life is pointless :'( EDIT: Well, looking at that question again it's quite stupid because n: p ratio is irrelevant once Z>=83.

Explain why ozone gas is more reactive than oxygen gas (2)

As I said, the equilibrium shifts (because H+ is being neutralised to H2O) such that citric acid approaches 100% ionisation.

LOL damnit I read Q8 wrong nice keep going!! Sigh im terrible

No the answer is definitely citric acid :) During titration, the neutralisation of the citric acid forces the equilibrium to shift forward (ionise). Thus triprotic takes preference over any diprotic/monoprotic acid. There was actually a HSC question that targeted this exact knowledge (2011 if...

wow < / 3

sure give me 10 minutes triprotic Edit: OOOOOOOOOOOOO GAME ON MISS SSH

@faisalabdul16, "These steps are necessary as it allows for maximum yield to be produced in a cheap and economically viable manner, thus leading to increased gains and profits." You missed an important environmental consideration o:

Well goodluck with this Q (taken from a 2014 commercial paper):

Was anyone else feeling the letters on the paper (it popped out like braille)? I was mesmerised for like 5 minutes Edit: looks like im a special child...

Industrial (Contact process): Did you guys learn about the several stages (the multiple layers of V2O5 catalyst and how each one has a dif temp condition) during the conversion of 2SO2 + O2 <--> 2SO3? Or did you learn that it was just simply in one step

A

To shift equilibrium fwd you mean!!
