The paper was so easy, didnt struggle on anything except why different chromatography paper changes the rf value. AQA redeemed themselves from Biology paper 2 with this one.

Did you get 0.313 for last question? 0.9 for Rf? 0.31 for X?

Did you do combined? Triple last question wasnt even maths

My "rate of reaction" was fast when answering those rate of reaction questions...
and then I see NPK fertilisers... :confused:

I somehow got lucky there though :redface:

how was it? what dd you guys get for calculation

Rate at 75 = 0.0051
7.37kJ for the reversible reaction thing
4.225g for the maximum mass of water
X = 7.2 in chromatography
Copper was 34.6%
RFM of the - |__| - rectangle thing = 14
Mass of ethanol was 1.34g for same energy
Energy from the graph with 8 carbons = 40.3
Mean for the 5 marker was 25 second
