AQA science double award modular, how'd it go?

Did people use data from the table to answer the ammonia conditions question?

I answered 450 C and 200 atmospheres because thats what we learnt.

(a) When temp increases = yield decreases.
(b) When pressure increases = yield decreases.

Well starch is a carbohydrate... I think you would get the mark yeah.

Nope, not really.

I got the same answer as that.

What did you get for the second bit, about the yield?
I got:
(a) When temp increases = yield decreases.
(b) When pressure increases = yield decreases.

yh it increases under higher presure im afraid...something to do with the system liking less particles (but bigger ones) in high pressure, in the same way as id spose id rather be in a small space with 3 fat people instead of 20 little people...thats how i remembered it anyway...and it worked with the temperature aswell: if its hot, the fat molecules will sweat and the equilibrium will stink of BO, so itll want more skinny hydrogen and nitrogen...but the exam was fine, only one i cudnt get was the opposite of polymerisation one, didnt have a clue

was the amount of light absorbed by the grass 2%?

and was the next answer after that 111?

when the temp increases, to forward reaction increases resulting in more ammonia, (however the reverse reaction also increases)... is this correct?

but i put increases for both... http://www.thestudentroom.co.uk/images/smilies/biggrin.gif

i put my answer as: lower temp and higher pressure?? is tht right??

the question was in what condition would the yield be more produce something like that i think...

I put 2% and 111 for the other too.
I think in question to the Haber Process question it was decrease for temperature and increase for pressure. I remember cramming it in befoore the exam.
I know that it increases for pressure, because of the likelihood of successful collisions is increased, due to the reduced amount of space. Something like that, correct me if I'm wrong!
Does anyone know if the hydrocaron question was cracking or polymerisation?
Or what the two balanced forces were for the Sun?
This paper was harder for me, even with a lack of Chemistry calculations and Physics formulas.
