26 paź 2020 · Hey everyone, in this video I’ll be covering what Gibbs free energy is, how it’s calculated and where it fits in on an energy diagram.
Gibbs free energy and spontaneity. When a process occurs at constant temperature T and pressure P , we can rearrange the second law of thermodynamics and define a new quantity known as Gibbs free energy: Gibbs free energy = G = H − TS. where H is enthalpy, T is temperature (in kelvin, K ), and S is the entropy.

13 maj 2023 · We can predict whether a reaction will occur spontaneously by combining the entropy, enthalpy, and temperature of a system in a new state function called Gibbs free energy (G). The change in free energy (ΔG) is the difference between the heat released during a process and the heat released for the same process occurring in a reversible manner.
The Gibbs free energy (G) of a system is a measure of the amount of usable energy (energy that can do work) in that system. The change in Gibbs free energy during a reaction provides useful information about the reaction's energetics and spontaneity (whether it can happen without added energy).
The Gibbs free energy of a system at any moment in time is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system. G = H - TS. The Gibbs free energy of the system is a state function because it is defined in terms of thermodynamic properties that are state functions.
Explore the concept of Gibbs free energy and its role in spontaneous chemical reactions. Understand how it's calculated and its relationship with enthalpy, temperature, and entropy. Discover how it influences metabolic pathways and the energy release in our bodies.
