Re: State Functions
Being a state function is important because it means that you can add or subtract. For example, enthalpy is a state function so if you are given the enthalpies for rxn1 and rxn2 you can add them together. Heat is not a state function so you can't simply add and subtract to find q.

Re: State Functions
State functions are important because they depend only on the initial and final and not the pathway taken. This helps us calculate enthalpy, Gibbs free energy, entropy, etc.

Re: State Functions
State functions help with calculations because we find values for a process when we can't use the exact path described, but can use initial and final states to calculate state functions like enthalpy, entropy, etc.
