Enthalpy vs. Entropy [ENDORSED]

[Leia_Acosta_1D]

What is the difference between enthalpy and entropy?

[Uma_Rajiyah_2A]

A listed in the course reader, enthalpy is the amount of heat released or absorbed at a constant pressure (qp= ΔH). It is a state property. In other words, a change in enthalpy is equal to the heat transferred at constant pressure. H=U+PV

A change in entropy, on the other hand, is equal to the heat supplied reversibly to a system divided by the temperature at which the transfer takes place. It is a measure of disorder. Low entropy means little disorder, high entropy means great disorder.

[Teja_Kadali_3A]

Enthalpy is a state function that keeps track of the energy of a system at constant pressure. A change in the value of the enthalpy of a system equals to the amount of heat released or absorbed at constant pressure. Entropy is a value that helps us determine the spontaneity of a chemical reaction.
