# Kinetics A2. I AM IN URGENT NEED OF HELP! I HAVE BROKEN TWO BIRO PENS IN ANGER! watch

1. You do B first.

Then A or C.

Then the other.

just no.
3. (Original post by phen)
this is mind-boggling. I'm baffled.. flabbergasted.

WORDS LACK TO DESCRIBE MY AMAZEMENT
oh are you trying to be mean to me again?
4. (Original post by Mathematics.)
just no.

I also do AQA son, got 100% when I had this as a mock.

I know what i'm doing...

5. Simply:
B - is found by exp 1 and 2
B increases by 4 rate increase by 4 .... hence B is one order
A - is found by exp 2 and 3
B is double so rate should become 6.4 but it is 4 times lower A is only twice as low .... hence A is two order
C - is found by exp 1 and 4
B increases by 3 so rate should b 2.4 and A falls by half so rate should fall by 4 to 0.6 as rate is already 0.6 .... C is zero

btw you dont need an extra box that is rubbish made up by your teacher , if you dont understand my explanation just ask .

Precisely.

This OP is a bit weird.

You HAVE to do B first...

DID YOU NOT READ THE OP? I ALREADY FOUND OUT B SO I DID DO IT FIRST. I just didn't know how to find A or C. jeez. And I'm not weird, in what way am I weird?

Listen you Kc da bucha, I don't have time/can't be bothered arguing.

10. (Original post by Mathematics.)
lol I only know one method. I'm a very stupid person.
hmm, since your username is mathematics, i suggest you look back to my post on the question(forgot which page it was already). I am not boasting, but really, i find the way i do it with ratios can save you a lot of time in a lot of situation with this type of questions.

looool, I will. You see, I love C3, C4, I can handle that. But physical chemistry =

I have asked for help what's Kc da bucha?

well you did get tons of help, so..

can you STILL not do this question?
14. When he means an extra box i think he wants to know how to work it out mathematically?

Sorry to hijack this thread but can someone tell me how to work out the orders? I can do it mathematically but that takes too long.
