# AQA CHEM4 - Filling in kinetic data into tables watch

1. I have no idea how to fill in the table. I would calculate k and then work backwards but seeing as you are supposed to fill in the table before calculating k I've come to an assumption there's a much easier way to do this. I just can't see it LOL also sorry if you have to tilt your head to extreme angles

2. Look at what the relationship is to the rate, the reaction order for the substance(s), and the concentration data you have. For instance, for the first gap, Y has doubled - so what will this do to the rate? given the order supplied in the equation.

Nothing as it's 0 order?
4. Yep, like the person above said, its all about the relationship between the values and the rate! For example, as Y is a zero order reaction, it has no affect on rate, therefore doubling the concentration of it would make no difference and the rate would remain the same! As X is second order, the relationship between this and the rate is a little more complicated, if you double X, you quadruple the rate! Good luck

Right that clears it up pretty much. Thanks
