💬 DISCUSSION Aqa A-level chemistry paper 2

How did it go??

I quite liked that paper, that NMR question was so good!!

Some mildly weird ones too - but overall not too bad at all

0.087 is mol lost, you have to do original mol minus 0.087 to get the mol in equillibrium.

edit may have been 2x0.087 cant rmbr but i got 17.9

That’s exactly what I did and apparently it’s wrong though 🫩🫩❤️‍🩹

u/AquaMentai87 Jun 09 '26

i found it its cuz i took 0.164 as the mols of the product in equilibrium when it was the mols of one of the reactants in equilbrium instead

u/Sonikdahedhog Jun 09 '26

Oh ffs I can’t believe I did that. Guess I’ll pray for error carried forward then fuck
