Since I have seen this come up a lot on specimen papers for depth I thought we could all post anything about the practicals and their limitations I don't know about you but my school didn't manage to finish all practicals and their write ups.
So if you have anything post below
THIS IS NOT A YEAR 9 THREAD THAT WAS A MISTAKE 😐

I found the gradients of my lines of best fits using the formula change in y / change in x. For this to work you have to have volume of gas on the y axis and time on the x axis. I plotted all the concentrations on the same graph and found the gradient of each line (and therefore the rate of reaction for each gradient)
