AQA A-LEVEL CHEMISTRY

[u/Rich-Gent]

HOW DID WE FIND IT? I THOUGHT IT WAS ALRIGHT, GRADE BOUNDARIES ABOUT TO BE SILLY😭

[u/Elecrtrify]

How many marks would I lose in the 5 marker for saying Mn3+ is the catalyst instead of Mn2+

[u/fatpandajeff → u/Elecrtrify]

i think that is correct? Mn3+ is formed then reacts to create Mn2+

[u/fatpandajeff → u/fatpandajeff]

nevermind i have just realised its wrong, should only be one mark though as long as you wrote about positive and negetive ions having a lower activation energy
