Hess’s Law and Hess Cycles (A-Level Chemistry)

Outlining Hess’ Law and the use of Hess cycles to find an unknown enthalpy change. The enthalpy of formation of propane is shown as an example and determined using enthalpy of combustion data for carbon, hydrogen and propane. 'Overall enthalpy change for the formation of products from reactants is independent of the route taken.’ Recap: 00:28 Hess’s Law: 02:07 Hess Cycles: 04:05 Enthalpy of Formation of Propane (example): 04:37 Summary: 10:35 Page on chemistrystudent.com: https://www.chemistrystudent.com/hess...
