Enthalpy path or state function
WebBefore we can answer this question, let's define path and state functions: path function are quantities that depend on the path that was taken from the initial state to the final state. For example, heat and work are path functions. state functions are quantities that don't depend on the path that was taken from the initial to the final state. They only depend on … WebTextbook solution for GEN CHEM LL PKG W/ALEKS CONNECT CARD 8th Edition SILBERBERG Chapter 13 Problem 13.37P.

Did you know?
WebFeb 19, 2024 · A Point function (also known as state function) is a function whose value depends on the final and initial states of the thermodynamic process, irrespective of the path followed by the … WebNov 17, 2014 · Suppose a person wants to reach the 4th floor from the 1st floor and he can take two ways: one through ladder and other one is through lift. In both cases, his initial and final state is same, but in both cases, the amount of heat he released is different. Therefore we can say that heat is path function not the state function.
WebAnswer (1 of 2): Enthalpy is a state function because it depends only on two thermodynamic properties of the state the substance is at the moment (like temperature and pressure, or temperature and entropy, or any pair of other state functions). It does not depend on the path followed by the subst... WebJan 30, 2024 · The sign of the reaction enthalpy changes when a process is reversed. H 2 (g) + 1/2O 2 (g) → H 2 O (g) ΔH° = -572 kJ. When switched: H 2 O (g) → H 2 (g) + 1/2O 2 (g) ΔH° = +572 kJ. Since enthalpy is a state function, it is path independent. Therefore, it does not matter what reactions one uses to obtain the final reaction.
A property whose value doesn’t depend on the path taken to reach that specific value is known to as state functions orpoint functions. In contrast, those functions which do depend on the path from two points are known as path functions.State functions are the values which depend on the state of the … See more As defined earlier, state functions are properties whose values do not depend on the path taken to reach that specific function or value. All … See more WebNov 16, 2014 · Heat & work are the forms of energy in transit. They appear only when there occurs any change in the state of system and the surroundings. They don't exist before …

In contrast to path functions, state functions are independent of the path taken. Thermodynamic state variables are point functions, differing from path functions. For a given state, considered as a point, there is a definite value for each state variable and state function. basic kleding damesWebSo, potential energy is a state function, not a path function. Path function in Thermodynamics. A thermodynamic property that depends on the path between the initial and final state is known as the path function.
