WebHess’s law is based on the fact that the enthalpy change for a reaction is independent of the number of ways a product can be obtained if the initial and final conditions are the same. A negative enthalpy change for a reaction indicates exothermic process, while a positive enthalpy change corresponds to endothermic process.
Web2. Find Net Enthalpy Change. Now that we have the official enthalpy values, we can use Hess’s Law equation to solve. ∆H net =∑∆H r = (-37 kJ/mol) + (-46 kJ/mol) + 65 kJ/mol = -18kJ/mol.
