A redox reaction involves the reduction of one substance (gaining electron(s)) and the oxidation (losing electron(s)) of another. Examples of reduction and oxidation are shown.

Combine the two given reactions like algebraic equations and write the net, or overall, redox equation.

(A)⟶(A^+)+(e−) oxidation of A
(e−)+(X)⟶(X−)reduction of X

net redox equation:

A + X ⟶ A^+ + X^-

Explanation:

Add the reactants from the oxidation and reduction equations then add the products.

A + e^- + X ⟶ A^+ + e^- + X^-

Cancel any species that appear on both sides of the equation. In this case, an e^- can be eliminated from both sides which leave us with:

A + X ⟶ A^+ + X^-

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.
