Current Year 13 Thread (2013/14) - Mark I

Hmm...not 100% sure. If you're asked to just use the rate equation, all I can think of is that the rate equation shows only the rate-determining step (i.e. the slowest step in the reaction) and so there must be more than one step. Not 100% sure though tbh

So from previous parts I know that:
Rate=k[ClO2]^2[OH-]
and k=200.

Later they tell me that 'In the overall equation, 2 mol ClO2 reacts with 2 mol OH- to form an aqueous solution containing chlorate (III) and chlorate (V) ions.

I found the overall equation: 2ClO2 + 2OH- -> ClO2- + ClO3- + H2O

(I thought this information isn't important because they asked how the rate equation provides evidence that reaction takes place by more than 1 step).


I'm doing OCR Chemistry A but I guess syllabus is similiar for all exam boards. But I don't find it too interesting (maybe that's because Chemistry isn't my favourite subject. )

Me too!

Chemistry is my degree choice hopefully

Ooh, I've just seen - well done!

Congrats!!

You must really love Chemistry then.
If I could choose again, I wouldn't have chosen Chemistry at A Level (I have an A* predicted but I don't find it enjoyable and when I do my study or revise for a test, I really have to force myself to do that).

Can Van Persie just choke now?

Did you watch it? So annoying.

Chances were there but we weren't getting in well enough. Bloody Bendtner...

It's just so annoying, if we played well I think we could have won that

I would like it if he disappeared from earth.


Absolutely gutted. We were so bad in the first half, it took Jack wilshere to actually get us going!! Kick in the teeth that RVP scored but we didn't deserve it in the end. Ozil has been anonymous recently.

Oh well, still top of the league...COYG



....dont even get me started on Bendtner

Özil started well in the season, then he's just...

We played ****. we need rest, and Walcott back.

we need a striker asap.

Yep! I didn't even think we played that bad, but I could see from the beginning that they were slightly stronger.

That dick!


I think that would be for the best. I still can't believe he betrayed us like that

Good to see many GOONERS about I can't believe how much he celebrates, the mans just a prick!! Oh well, we'll see who's celebrating come the end of the season

I got on the waiting list for a season ticket yesterday so when I leave uni I should have one waiting for me!!...not that I'd have time to go

Addicted to Breaking Bad...kinda makes me wish I'd tried in chemistry

That show needs a warning on it, it's too addictive I don't even really watch TV and I got so addicted that in the first 3 weeks of sixth form I watched ALL OF IT :O ...lets just say that also coincided with a dramatic decline in school performance

Haha I was exactly the same at the start, made me want to become a meth maker

Benzema needs to come in. We need theo back i agree, and Podo/Ox too!!

Hate losing to United, really ruins the day haha!
