Berechnen Sie die Standard-Reaktionsenthalpie durch Subtrahieren #DeltaH_f# der Reaktanten aus den Produkten. Folgen Sie einem ähnlichen Verfahren, um die Standard-Reaktionsentropie zu berechnen (#DeltaS#). Berechnen #DeltaG^0# für die Reaktion mit der Gleichung #DeltaG^0=DeltaH^0-TDeltaS^0#.The reason for this is that they are a measure of the maximum work (in the case of ΔA Δ A) or non p-V work (in the case of ΔG Δ G) that is available from a process. To show this, consider the total differentials. First, consider the differential of A A. dA = dU − TdS − SdT d A = d U − T d S − S d T. Substituting the combined first ΔG = −nFE Δ G = − n F E. If all of the reactants and products in the electrochemical cell are in their standard states, it follows that. ΔGo = −nFEo Δ G o = − n F E o. where Eo E o is the standard cell potential. Noting that the molar Gibbs function change can be expressed in terms of the reaction quotient Q Q by. ΔG = ΔGo + RT ln In this chapter, we learn to relate the reaction quotient (Q) to Gibb's free energy mathematically through the expression ΔG = ΔG° + RT ln Q. We also learn about the relationship between the equilibrium constant (K) and ΔG°, which can be expressed through the equation ΔG° = -RTlnKeq. A negative value for ΔG indicates a spontaneous process; a positive ΔG indicates a Acid-Base Disorders Acute Kidney Injury (AKI) Brought to you by Merck & Co, Inc., Rahway, NJ, USA (known as MSD outside the US and Canada) — dedicated to using leading-edge science to save and improve lives around the world.
