When balancing a redox reaction, begin by separating the reaction into . Balance each of these in terms of .
Multiply by some factor if necessary so that the number of appearing in both is the same. Add these together, canceling out any terms that appear on both sides of the final equation.
Provide the coefficients needed to balance the redox reaction given.

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.
