Yup, enthalpy is a state function, which explains why we are able to use Hess's law to calculate the reaction enthalpy.

Re: Is enthalpy a state function?
A state function describes the equilibrium state of a system. Internal energy, enthalpy, and entropy are state quantities because they describe quantitatively an equilibrium state of a thermodynamic system, irrespective of how the system arrived in that state.

Re: Is enthalpy a state function?
You can think of the enthalpy of formation as the heat stored in the bonds of the molecule, formed from its components.

Re: Is enthalpy a state function?
we use the hess's law approach to add up enthalpies, which is only possible because it is a state function
