Higher Chemistry Assignment

I'm doing my higher chemistry assignment on the effect of temperature on enzyme rate (which seems more biology related but it's what my teacher made our group do) and i'm struggling to know how I would do the analysis seeing that the results are a curve so do not give directly or inversely proportionate results - is there any specific vocabulary i'm expected to use? I'm also confused on how the SQA want us to compare values in our analysis as the understanding standards website doesn't give much of an indication as to what comparisons are appropriate or not.
I've also found it difficult to find an appropriate second source that isn't behind a pay wall, any ideas?

Just recently did my higher assignment, I struggled on analysis too but I'll try to help!!

Maybe you could say "as x increases, y increases, until point A. After that, as x increases, y decreases" or something along the lines of that. You should compare both with the second source and also within your own data set. So you could maybe compare how at first it increases and then it decreases, and why that is? Then say what is similar or different about your graph and the second source graph (e.g. they both follow a similar curve, but mine is steeper.) That's the sort of thing I did, anyway. Hopefully this helps a bit !!

that does help, thank you so much!

Hello! I hope I'm not too late, haha. I also do higher chemistry and just recently did my write up for my assignment.

Analysis is, in my opinion, the trickiest mark to get in assignments. Looking at assignments that were done on experiments similar to your one on the Understanding Standards website is something I'd heavily advise as you can see what they did right if they did get the mark or what they did wrong and how to fix it.

What the SQA want for your analysis is two main points. Comparison between the data sets and comparison within the data sets. It sounds a lot more complicated than it actually is. Essentially, what you have to do is compare the trends shown (between) - which for me was the trend of orange > lemon > lime for vitamin C content - and then compare individual values (within) - which for me was things like how my experimental value for lime was almost double what my source's value was, etc.

Like I already said, I would heavily advise looking at the understanding standards website for a similar experiment/assignment so you can get an idea of what will get you the mark. Good luck!
