Science / Chemistry / Hesss Law: The heat released or absorbed by a process is the same no matter how many steps the process takes. For example, given a reaction A rightarrow B, Hess's law says that deltah for the reaction is the same whether the reaction is written as A rightarrow C rightarrow B or as A rightarrow B. This is the same as writing that deltah(A rightarrow B) = deltah(A rightarrow C) + deltah(C rightarrow B).
