    Pb02 + Pb + 2H+ + 2HSO4- ----> 2PbSO4 + 2H2O
    was the other way round, the question asked for when it was recharged, aka the reverse reaction, that is the forward reaction that you put.

    yeah, I thought that it was the reverse too as it did ask for when it would be recharged

    It's usually around 82 raw marks 108/120 UMS for A* or 73 and 96/120 for A.

    This paper was average so I'll be looking around those regions.

    *sigh* Somewhat delayed reaction as I’ve been recovering from the rapid succession of exams last week. For that same reason, I was about as ‘on the ball’ as a dead seal during the Chemistry exam. Consequently, I’ve made a few silly errors (e.g. something possessed me to write Standard Hydrogen Electrode instead of Hydrogen Fuel Cell for the constant EMF graph. I then went on to explain a hydrogen fuel cell...) but I found the exam intriguing irrespective of difficulty or oversights on my part.

    I wish everyone well, I’m sure that self-deprecation and anxiety are blinding many people to their innate talents. I’m sure that personal marks will be far higher than people are expecting. Good luck and have a truly wonderful Summer.

    I've seen it in a past mark scheme saying 'accept forward reaction' on the RHS.

    Where it asks for an ionic equation and you do a normal equation would u still get the
    Marks ? My friends said yes but I'm not sure tbh what do u think ? X

    Umm i don't think you would get the marks, the question was specifically asking for the ionic equation, but fingers crossed!

    This.

    I made the same mistake but if the balancing is correct then they normally have a separate mark for that. So if you did the full equation and balanced it correctly I assume they will give you a mark.

    The two equations were only 1 mark each if i remember corectly?

    I thought i'd get it wrong but if its worth two, then thats good!

    Nah they have to be more than one because on all the past papers they had a separate mark for balancing too. So it has to be at least two marks because those equations required balancing.

    Yeah I know. Though I'm not with Edecxel, their boundaries for maths are certainly ridikuluz!

    think the grade boundaries are fair, considering the comments people made about the Biol5 exam...

    seems the majority found it tricky..

    anyway, good luck with the rest of your results people!!!
