Cycloneash's question thread

Hey guys, I just have a few questions.. some may be pretty easy but anyway.

1) What exactly happens with water and the equillibrium constant, I have read that it can be ignored but what actually happens?

2) For the exam are we expected to know the 12 principle of organic chemistry, for example Prevent waste, design safer chemicals etc..

3) How does the rate of reaction specifically link with providing a catalyst, I know it creates an alternative pathway but how does it exactly work?

4) Also, how do you particularly know if an acid is weak or strong, is it just knowledge of the chemicals? I can't remember..

Thank you.

2. No
3. so a catalyst provides an alternate reaction pathway -yep.
From memory, i think its based upon the fact that, a substance adsorbs to the surface of the catalyst, where the bonds in the substance break off and so the substance becomes smaller -> more surface area - > rate of reaction increases.
i think thats it, but not 100% sure...
someone may wanna read over that and check!

Thanks for the quick reply and thank god, I hate memorizing facts like that
and yeah that's what I thought it was too, I was just getting a second opinion, it seems right.
