anyone else revising kinetics?
whats the best way to revise it?
Just finished revising it, was quite easy.
You need to make very few notes and just make sure you know how to work out the orders and constant. Plus a little bit about how SN1 and SN2 relate to the rate equation.
Also make sure you know breifly about how to measure the rate of a reaction i.e measuring gas evolved, titrating and using colorimeters.
A brief description of what i think they are;
SN1 means one reactant appears in the rate equation so the rate depends on the concetration only one reactant.
eg the formation of a carbocation or the formation of an electrophile.
SN2 means two reactants appear in the rate equation so the rate depends on the concentration of two reactants. Meaning a transistion state is formed and that the formation of it is the rate determining step.
I hope that makes sense.
Can I ask you if you have any unit 5 and 6 chemistry markschemes? I really need them urgently.
Ah its gr8! Thank you so much.
