What does the gibbs free energy predict?
It predicts whether or not a reaction will be spontaneous.
How does Gibbs free predict spontaneity?
If G < 0, the reaction is spontaneous.
Why Gibbs free energy must decrease in a spontaneous reaction?
Gibbs free energy (G) represents the maximum reversible work that can be performed by a system at constant temperature and pressure. In a spontaneous reaction, the system tends to move towards a state of lower energy and increased entropy, which corresponds to a decrease in Gibbs free energy. A negative change in Gibbs free energy (ΔG < 0) indicates that the reaction can occur spontaneously, driving the system towards equilibrium. Therefore, for a reaction to be spontaneous, Gibbs free energy must decrease.
How does Gibbs fee energy predict spontaneity?
Gibbs free energy (G) is a thermodynamic potential that predicts the spontaneity of a process at constant temperature and pressure. A negative change in Gibbs free energy (ΔG < 0) indicates that a reaction is spontaneous, meaning it can occur without external input. Conversely, a positive ΔG (ΔG > 0) suggests that the reaction is non-spontaneous and requires energy input to proceed. When ΔG equals zero, the system is at equilibrium, and no net change occurs.
What is the name and symbol of the single thermodynamic quantity which determines whether or not a reaction is spontaneous?
The name of the single thermodynamic quantity is Gibbs free energy (G). The symbol for Gibbs free energy is ΔG (delta G). The sign of ΔG determines whether a reaction is spontaneous (negative ΔG) or non-spontaneous (positive ΔG).

What is the difference between Gibbs free energy and standard free energy, and how do they relate to each other in chemical reactions?
Gibbs free energy and standard free energy are both measures of the energy available to do work in a chemical reaction. The main difference is that Gibbs free energy takes into account the temperature and pressure of the system, while standard free energy is measured under specific standard conditions. In chemical reactions, the change in Gibbs free energy determines whether a reaction is spontaneous or non-spontaneous. If the Gibbs free energy change is negative, the reaction is spontaneous, while a positive change indicates a non-spontaneous reaction. The relationship between Gibbs free energy and standard free energy lies in the fact that the standard free energy change can be used to calculate the Gibbs free energy change under any conditions.
Gibbs quantity of maximum possible work?
Gibbs free energy represents the maximum reversible work that can be extracted from a system at constant temperature and pressure. It combines the system's enthalpy and entropy to predict whether a reaction is spontaneous. The change in Gibbs free energy (∆G) determines whether a reaction will proceed spontaneously or not.

What is Gibbs Free energy?
The usable energy released or absorbed by a reaction.

Is the Gibbs free energy negative in the spontaneous reaction?
Yes, as long as the entropy of the universe increases.
How does the Gibbs free energy predict spontaneity?
It tells if the reaction will process spontaneously or not
What is a negative Gibbs free-energy value an indication of?
A negative Gibbs free-energy value indicates that a reaction is spontaneous, meaning it can proceed without requiring external energy input. It suggests that the products of the reaction are more stable than the reactants at the given conditions.
Using the Gibbs free energy equation what is the temperature range for which the oxidation of lead is spontaneous?
The reaction is spontaneous below 554.8/0.1975 K.
What are the units of Gibbs free energy and how do they relate to the thermodynamic properties of a system?
The units of Gibbs free energy are joules (J) or kilojoules (kJ). Gibbs free energy is a measure of the energy available to do work in a system at constant temperature and pressure. It relates to the thermodynamic properties of a system by indicating whether a reaction is spontaneous (negative G) or non-spontaneous (positive G) under given conditions.
