Entropy says that any closed system will become more disordered over time. If there are only a small number of parts in the system (say 3), then there is 1 correct order (123), and 5 incorrect orders (132, 213, 231, 312, 321). If the system randomly changes order, there's still a good chance of it changing from a disordered state to an ordered state. That would make entropy wrong. However, in a system with billions of variables, the chance of returning to an ordered state is negligible. In a system like this, you can count on the rule of entropy. That's why entropy depends on the amount of parts in a system.

Using Gibbs free energy equation what is the Gibbs free energy change for the synthesis of carbon disulfide at 25C?
δg = (-992.0) - (298)(-294.6)(1/1000)
What is a negative Gibbs free-energy value an indication of?
Spontaneous reaction
What does Gibbs free energy depends on?
it depends on the entropy and enathalpy of the reaction
What is true about the numerical value of the Gibbs free-energy change for a spontaneous reaction?
B
What information does gibb's free energy give about reaction?
When the Gibbs free energy for a reaction is greater than zero, the reaction is "disfavored" - won't proceed in that direction - in fact it may try go in the reverse direction if possible. When the Gibbs free energy for a reaction is less than zero, the reaction is "favored" - it should proceed as written spontaneously. When the Gibbs free energy for a reaction is exactly zero - it is in equilibrium, with the forward and back ward reactions occurring at the same rate.
What is the Gibbs free energy of the reaction at 300K?
150
Use the Gibbs free energy equation shown below to find the Gibbs free energy change for the formation of potassium chloride at 25°C?
-225.3 KJ
Using Gibbs free energy equation what is the Gibbs free energy change for the synthesis of carbon disulfide at 25C?
δg = (-992.0) - (298)(-294.6)(1/1000)
Where can one learn more about the Gibbs Free Energy theory?
One may go to the local library to research Gibbs Free Energy theory. One may also look towards Wikipedia, Ebooks, Boundless or Chemistry About to find information about the Gibbs Free Energy theory.
Is Gibbs free energy constant?
In general Gibbs free energy is NOT constant. Gibbs free energy can be translated into chemical potential and differences in chemical potential are what drive changes - whether it be chemical reactions, phase changes, diffusion, osmosis, heat exchange or some other thermodynamic function.
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.
Why is hydrogen combustible?
Fundamentally, because the Gibbs free energy of elemental hydrogen and oxygen is substantially greater than the Gibbs free energy of the water formed by their chemical reaction, and the activation energy for the reaction is not excessively high.
What is the value equal to the enthalpy minus temperature times entropy?
free energy. this is gibbs free energy in biological systems
What does the gibbs free energy predict?
It predicts whether or not a reaction will be spontaneous.
What does Gibbs's free energy depend on?
it depends on the entropy and enathalpy of the reaction
What is a negative Gibbs free-energy value an indication of?
Spontaneous reaction
What does Gibbs free energy depends on?
it depends on the entropy and enathalpy of the reaction
