    Same!- although I messed up a bit on the 6 mark question but should still get like 4 I think

    Me too! I realised in the last minute of the exam that I'd mixed up the two substances in the 6 marker, so I had to rush back XD

    Ok, if I actually managed to get it right- I said roughly 11400 years but below that as the half life was 1.8

    I think i managed to get something similar to that However, lots of people said they got 10,000... oh well. What was your answer to the question on the gas produced in a reaction being the same using different catalysts? x

    Yay - I put that a catalyst can only speed up a reaction so therefore cannot actually add to the amount of gas being produced therefore in both reactions that same amount of gas would eventually be produced
