Homework Statement
For the reaction 2H2O(l) -> 2H2(g)+O2(g) delta H = +571.5 kJ
If the reaction is carried out in an insulated chamber what effect would the reaction have on the temperature in the chamber? Why?
The attempt at a solution
I can't seem to get my head around this one. I know the sign on the enthalpy change is from the point of view of the system...but what really qualifies as the system and the surroundings if there is no real boundary between them?
