Industrial applications of Le Chatelier's principle..

Do we need to know both of these?

The haber process for the manufacture of ammonia
The contact process for the manufacture of sulfuric acid

or can we just learn one? cheers

MKay

I was wondering the same myself, someone help.....

d4gurl

I just rang my friend she said she just did the haber process but I dnt know im still skeptical!!ABERCROMBIE CA BHFUIL TU??

I think it's just one you need to know.
but I haven't come to that chapter yet, so I'll wait and freak out when I do

niamhy101

i'm not sure, we only did the haber process but it doesn't say anything bout only doing one. Sure the SO3 thing isnt that hard, just remember vanadium pentoxide is the catalyst and the conditions are high pressure and low temp. tho in reality its only atm pressure and 450 C then mix it with water to get H2SO4

Guys can I get away with not learining the gas chapter? I HATE IT!

nedward

Yeah, sure.

Edit: Not being sarky, I'd say gases can be skipped.

goodgod3rd

I'd say gases will come up,
as for the two, in my (under revised)mind, they both need the same conditions. (as in high pressure, low temp)

the catalysts :< dammit i forget... *runs to book*

i personally goin over everything, but i do belive ya can get away with out two things, if your stuck for time...

what chem exps do ya think will show their worrysome heads?

ethanoic acid+tests
neutrislation in a cup...
iodine vs sodium thios sulfatE?
water crystalisation

grimloch

If ethanoic acid and all its crappy tests show their head I'm going to scream.

helles belles

im nearly 100% that you need to know both the contact and the haber process.

Whats the test with ethanoic acid, I thought they were only for aldehydes and ketones?

nedward

I don't think tomorrow's exam will be in any way predictable. Physics was as not predicted, same with French, Geog, Irish (my subjects). Hope to God that's true
and eth. acid doesn't turn up.

goodgod3rd

well i wasnt predicing.

i was guessing.... i think it will cause our teacher does. when ya look back.. it hasnt come up, and the other organic's mostly have....


but true, they messed bio around...exp wise (for me- wasnt expecting that format -nice unexpected mind you)

really , its worth knowing, all of it... the whole syllbus! lol
but last minute.. cant hurt.

look back, you see that it hastn come up yet.. ethanal, soap, and the almunds.. have. its my bet....

fatal

you definitley need to leanr both..they can ask either.....it only takes an extra few mins to learn the one you dont know

d4gurl

but the haber proces is so much more easier!i fel sorry for my friend she only learned one cuz dt wat her teacher did! tnk god for Tara Lyons - Id be failing (touches wood) if it werent for her

goodgod3rd

which industry option did ya do??
they are boht the same, really, only .. a varation in temp and catlyst.

d4gurl

haber i tnk!haha i plan on doin the option on d bus!cnt wait!!hahah!

Faerie

We didn't even do Industrial chemistry or electrochemistry. There's plenty of choice on the paper so maybe at this stage (like 3 hours before the exam!) you should concentrate on revising stuff you know and Experiments.

helles belles

you have to love tara lyons. Scariest woman alive, but the best ****ing teacher available!
pity she didnt give any predictions though!
im looking over the option for the first time now!
i still have to do water, gas laws and rates of rxn. and i need to look over organic.
better get off the net i guess......

d4gurl

two more titrations to go!here Im not doin any water titrations that said d bastards makin d paper wil put it up this year and laugh at me!ahh!!i just cant wait for tonite im nt even bothere ne more!watever happens happens! (goes and runs to studys and tries to recuperate from nervous breakdown!!)

She predicted that water of crystallisation titration, to my delight.

d4gurl

No one can compare to Tara lyons!!! first year in my life that im passing chemistry!!
