That was very good - pretty much all the questions were similar to past papers anyway.

Really Good exam. X = 10 BTW

Were we supposed to use 14.7 or 15 for the delta H? I used 15 and got 3667 kJ/mol

i used 14.7 because it gives more accurate results i think

It was probably better to use the Q you calculated but they will definitely allow using 15kJ

I talked about how bromine can’t displace chlorine cos it’s more reactive, so solution stays orange
then I said bromine displaces iodine as it’s more reactive, turning the solution brown
This shows the order of reactivity is: chlorine, bromine then iodine
BTW i fleshed our each point but that was the basic structure
