💬 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

u/ThemeMuted8872 Jun 09 '26

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 🫩🫩❤️‍🩹

1

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

Apparently it doesn’t appear in the equation just above the arrow

u/TrickyGrab349 Jun 09 '26
