A thermochemical cycle shows
the different possible routes that a reaction can take from starting reactants to final products
definition for Hess’ law
The enthalpy change in a reaction at constant pressure is independent of the route taken
If an equation for a reaction is balanced, then both the reactants and products will be formed from the same…
