What did you think overall.

I thought it was pretty much on par with 2001 and 2002. There was a little bit of everything from the option which was good cause I made sure I learnt everything in the option equally.

Yeh, pretty specific, bit of everything.
It was OOOOHHHHK.

I thought it was good, what did you people get for the equilibrium constant, I think I stuffed it up!

 

[vegeta_316]

800 for the equillibrium constant. Most people seem to have got that so it's safe to say it was the right answer. How much was that worth?? I forgot my paper at school.

lol no way it was 800. There's a special method for doing these, good thing I know how to do them. I forget what I calculated now though...

I got 6.4

 

[vegeta_316]

There were some posts in the other thread that came up with an answer of 800.
I'd do the question again only I don't have the exam paper.

Was anyone eles not expecting a soap question quite like that. I kinda had to make up my answer.

Also my teacher said the last question was not part of the sylabus. Didn't stop me from writing a fairly good answer.

 

[sunken eyes]

yeah, the last question sucked hardcore. they did all wired stuuf. they tested the finge of the syllabus, not what we'd done all year i reckon. it was an easy test, but it was still shithouse. not impressed with any of the scince tests so far.

[Survivor39]

It's 800.

 

[spark]

I got 50. Blah.

 

[hellohello]

WHAT IS THE RIGHT ANSWER can ppl show working

 

[vegeta_316]

Ok can someone write up the question please. I'll be more than happy to answer it.

 

[guesswho]

i got 10 ( but was about to put 800,,,damn i mixed it up if it is 800)

 

[sneaky pete]

post below mine has correct reproduction of question

 

[Lord Ac]

THIS IS THE REAL THING:

equation: _____ 2NO + O2 <-> 2NO2_____
mole ration:____ 2____1_______2_______
initially:_______0.25__0.12_____0.00____
equilibrium:____0.05__0.02_____0.20____


K = (0.20)^2 / (0.02)(0.05)^2
.: = 800

Ac

 

[vegeta_316]

yep that's it.

 

[braindrainedAsh]

Yep that's what I got.

 

[Survivor39]

I agree with Lord AC
