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.
How the second law of thermodynamics helps us determine whether a process will be spontaneous, and using changes in Gibbs free energy to predict whether a reaction will be spontaneous in the forward or reverse direction (or whether it is at equilibrium!).
The standard Gibbs free energy of formation of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of that substance from its component elements, in their standard states (the most stable form of the element at 25 °C and 100 kPa).
Intuition behind why spontaneity is driven by enthalpy, entropy and temperature. Introduction to Gibbs free energy. Created by Sal Khan.
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.
How is the Gibbs free energy of a system different from its enthalpy? What different usages or significances would they have?
26 lut 2022 · The free energy graph can be used to determine whether the reaction will be spontaneous or not by evaluating the ΔG. ΔG can be found by subtracting the free energy of the reactants from the free energy of the products.
