Hess’s Law

Postby Riley Joe 2K » Fri Mar 15, 2024 11:59 am

How does Hess's Law help us determine the enthalpy change of a reaction?

Hess's law is due to enthalpy being a state function, which allows us to calculate the overall change in enthalpy by simply summing up the changes for each step of the way, until product is formed. All steps have to proceed at the same temperature and the equations for the individual steps must balance out.
