Jul 26, 2021 · It is interesting to note that $ΔH$ (enthalpy change) and $ΔS$ (entropy change) values for any chemical reaction remain nearly constant even on varying temperature.

Jan 7, 2014 · 1 Internal energy and enthalpy. I am finding it hard to distinguish between the two. Confused. Can someone explain me the two terms and difference between them? I tried learning …

Mar 2, 2022 · The change in entropy $\Delta S$ between an initial- and a final thermodynamic state of a system can be determined by calculating the integral of dQ/T for a reversible path between the initial …

Dec 3, 2018 · Enthalpy is simply a useful derived property for analyzing certain type of thermodynamic problems. It is not a fundamental property such as internal energy, entropy, pressure, volume and …

Apr 16, 2016 · Entropy is the cumulative filling of energy destinations between absolute zero (motionless) and a given temperature. Heat capacity is the rate of change of entropy with …

Sep 5, 2023 · I don't understand the reasoning in the question. You give an enthalpy change at constant pressure and then ask whether this implies that the value is independent of pressure? If you …

As we increase the entropy going from the solid to liquid, we have to do so under the condition of no change in free energy, thus the enthalpy has to exactly match the entropic free energy TS.

Mar 16, 2024 · 2 I'm curious about how entropy is defined within chaos theory. Are there analogous laws similar to the second law of thermodynamics? How do we define steady-state or equilibrium within …

Dec 24, 2019 · 5 In statistical mechanics, entropy is an extensive property of a thermodynamic system. Enthalpy a property of a thermodynamic system, is equal to the system's internal energy plus the …

Jan 31, 2019 · Entropy is a function of thermodynamic equilibrium state, or (generalized entropy) integral of local entropy density where locally the medium is in thermodynamic equilibrium. In general, …
