Explaining Hess's Law with enthalpy = a state function?

Postby JeremyPark14B » Mon Feb 11, 2019 1:10 am

I saw this on the learning outcomes for thermochem; how does enthalpy being a state function justify Hess's Law?

This just touches on the idea that because enthalpy is a state function, the path taken to reach a certain enthalpy doesn't matter so enthalpies can be calculated by adding together the enthalpies of multiple steps of a larger reaction.

Enthalpy is a state function, so it doesn't matter what path it takes, as long as it reaches enthalpy

Are the basic units for enthalpy always kJ?
