Chemguide: Support for CIE A level Chemistry
Learning outcome 8.1(b)
This statement is about the effect of concentration on rates of reaction. This particular statement doesn't involve any calculations; those are reserved for later statements in the second half of a two year course.
Before you go on, you should find and read the statement in your copy of the syllabus.
You will find this explained on the page about the effect of concentration on rates of reaction.
You should also read the page about the effect of pressure on rates of reaction. This isn't specifically mentioned by the syllabus, but you will need to know about it anyway for work on some industrial processes.
You will find that the pressure page is almost a repetition of the concentration page in places. You aren't likely to need the bit about pV=nRT, but you do need to know that pressure has an effect because it changes the concentration of substances in the gas.
