Equation of State Function
State functions can be measured as integrals because integrals depend on only the function, its lower limit and upper limit. In the same way, state functions also depend on the property, its initial value and final value.
Consider a state function integral of enthalpy H, and t0 represents the initial state and t1 represents the final state is given by the following equation:
This equation is similar to the equation of enthalpy:
ΔH = H final − H initial
Thus, the change in state function is the difference between its final value and initial value.
State Functions
State Functions are the functions that are independent of the path of the function i.e. they are concerned about the final state and not how the state is achieved. State Functions are most used in thermodynamics. In this article, we will learn the definition of state function, what are the state functions in Thermodynamics, and how they differ from path function.
