What do u mean by entropy and enthalpy? write some differences between them.

Explanation:

Entropy: a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.

Enthalpy: a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.

Differences: The main difference between entropy and enthalpy is, entropy is used as a measurement of the disorder or the randomness of a chemical process while enthalpy is used as a measure of the heat change of a chemical reaction or the change in internal energy of a reaction under constant pressure. Entropy is measured in JK-1 and Enthalpy is measured in Jmol-1

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
