Flashcards in 9.4 - Hess's Law & Enthalpy Cycles Deck (3)
Define Hess's Law
If a reaction can take place via 2 routes, and the starting and finishing conditions are the same, the total enthalpy change is the same for each route.
If enthalpy change of combustion is,
reactants > products,
denoted by A, what is the formula for the indirect route?
A = B-C
