Conservation of Energy in chemical reactions, Hess`s Law
... Here is an example of how Hess’s Law can be used to figure out the H for a nearly impossible reaction to do in the lab… forming diamonds from ordinary graphite ! Here is the equation: C (s, graphite) ---> C (s, diamond) H° = ??? kJ Hess' Law offers a way out. If we could show this reaction as the ...
