Aug 16, 2023 · 4.1: Free Energy Functions. In the previous chapter, we saw that for a spontaneous process, ΔS for the universe > 0. While this is a useful criterion for determining whether or not a process is spontaneous, it is rather cumbersome, as it requires one to calculate not only the entropy change for the system, but also that of the surroundings.
Aqueous is a state of being dissolved in water and uses the state symbol (aq) which originated from the Latin word for water – Aqua. This word can often be found at number one on the ingredients lists of inedible items like shampoos and conditioners. Water is an example of a compound comprised of hydrogen and oxygen bonded covalently.

A function of state is one in which the differential change is determined only by the end states and not by intervening states. Most thermodynamic variables are state functions and hence property changes are determined by the end states and not by the process path. Notable exceptions are work and heat.
State Functions A state function is a relationship between thermodynamic quantities—what it means is that if you have N thermodynamic variables that describe the system that you are interested in and you have a state function, then you can specify N ¡1 of the variables and the other is determined by the state function.
Oct 23, 2015 · This is because a state function is a value in which is dependent on the state of that particular system. The value of a change in a state function is always the difference between the final and initial values. It is important to note that the value depends only on the state of the system, not on how the system arrived at that state.
