Gibbs energy change, also known as Gibbs potential, is a function defined by J.Willard Gibbs to account for the change in both entropy and enthalpy. This function is independent of variations in pressure and temperature and depends only on the state of a system, not on how this state has been attained.
What is Standard Gibbs Free Energy of Formation?
The Gibbs energy change associated with the formation of a compound from its constituent elements under standard conditions is termed as Standard Gibbs free energy of formation. It corresponds to the rate of achieving an equilibrium.
What does Gibbs Free Energy Equation indicate?
A thermodynamic system is said to be in equilibrium if its intensive properties (temperature, pressure) and extensive properties (U, G, A) are constant. If the Gibbs free energy is zero then the system is said to be in equilibrium.
What does a negative value of ΔG indicate?
A negative value of ΔG indicates that the reaction is favourable or spontaneous.
What does a positive value of ΔG indicate?
A positive value of ΔG indicates that the reaction is not favourable or non-spontaneous.
What does a zero value of ΔG indicate?
A zero value of ΔG indicates that the reaction is said to be in equilibrium.
