What is the Gibbs Free Energy Calculator & How does it work?

Gibbs free energy (ΔG) is a thermodynamic potential that measures the maximum reversible work that can be done by a system at constant temperature and pressure. It is crucial in determining the spontaneity of chemical reactions.
The change in Gibbs free energy can be calculated using the formula:

ΔG = ΔH – TΔS

ΔG = Change in Gibbs free energy
ΔH = Change in enthalpy
T = Temperature (in Kelvin)
ΔS = Change in entropy

A negative ΔG indicates a spontaneous reaction, while a positive ΔG suggests the reaction is non-spontaneous.
