Expert Answer
- Entropy is basically a term for disorder or randomness while enthalpy is defined as the total heat content of a system at constant pressure equivalent to sum of internal energy and pressure-volume energy is called the enthalpy of the system and is given by the following equation
H = U + PV,
Here U is the internal energy.
- S.I. unit of Entropy is Joules per Kelvin while S. I. unit of enthalpy is Joule per kilogram.
The Gibbs free energy of a system at any moment in time is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system.
G = H - TS
