    What did people get for (delta)H of reaction? I think I got 58.5 or something like that. Worked out q=4000(odd)J and divided by the mol of the substance you were provided with.

    Minus 58.5 as delta H is negative

    Minus 58.8 as delta H is negative
    Why? The mixture increased in temperature meaning it was an endothermic reaction?

    No mixture increased in temp suggesting heat was released, therefore exothermic

    Increase in temp means heats being given out. So its exothermic

    As for the grade boundaries, I do think that they will remain on the same level , so >56 will get you an A.

    Agreed, it was probably in between the difficulty of a F321 and F322 paper (as expected with it covering everything)
