Thermodynamics- Chemistry. Nature tends to move spontaneously from a state of lower probability (order) to one of higher probability (disorder); systems overtime without outside influence will move.

The chemicals fine-tuned themselves naturally. These reactions generate heat that obeys the second law of thermodynamics; entropy will always increase in the system and the chemicals would.

S for a chemical reaction is therefore equal to the difference between the sum of the entropies of the reactants and the products of the reaction. S = S(products) – S(reactants) When this difference is measured under standard-state conditions, the result is the standard-state entropy of reaction, S o. S o = S o (products) – S o (reactants)

Key Points. Redox reactions are reactions that transfer electrons between species. The Nernst equation allows us to calculate the reduction potential of a redox reaction under “non-standard” conditions. When the system is at equilibrium, the Nernst equation can be simplified and written in terms of the equilibrium constant, K, which, in turn,
