Only answer in 1-2 sentences.. that’s fine :) (WILL MARK BRAINLIEST) will appreciate it thanks!

a chemical change is usually an irreversible chemical reaction. an example of this is rusting.

a physical change is usually visible while a chemical change isn't. also, a chemical change is irreversible while a physical change is.

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.
