Unit 1 Electrochemistry Ppt Pdf Redox Electrochemistry Uses of standard electrode potentials • use standard electrode potentials to predict whether an electrochemical reaction at standard state conditions will occur spontaneously. This document provides an overview of electrochemistry. it begins by defining electrochemistry as the study of chemical reactions at the interface of an electrode and electrolyte involving the interaction of electrical and chemical changes.

The standard cell potential (the cell potential measured when all the species are in their standard states) is given by: e°cell = e°cathode e°anode cathode: cu2 (aq) 2e cu(s) the shorthand notation for this cell is: zn(s) | zn2 (aq) || cu2 (aq) | cu(s) the cell potential, e, is a measure of how well a cell reaction can push and pull electrons through a circuit reduction occurs at the electrode with higher potential and oxidation occurs at the electrode with the lower potential unit of potential is the volt (v) and unit of charge is the couloumb (c) these are related by: 1v = 1j c the charge of one mole of electrons is given by the faraday constant, f (f = 96,500 c mol 1) the more negative the reduction potential is, the more readily the element acts as a reducing agent, i.e. is itself oxidised we can combine the standard cell potential and faradays constant to give us an equation for Δg° Δg° = n f e°cell where Δg° is the change in gibbs free energy n is the number of moles of electrons f is faradays constant e°cell is the standard cell potential have relationship between gibbs free energy and equilibrium constant: Δg° = rt lnk Δg for a reaction depends on the concentration by: Δg = Δg° rt ln q where q is the reaction quotient = [product] [reactant] but Δg = n f ecell and Δg° = n f e°cell dividing across by nf gives: ecell = e°cell – rt ln q nf nernst equation nfecell = nfe°cell rt ln q i.e. the cell potential at any conditions depends on the potential under standard state conditions and a term for the potential at nonstandard state conditions question which of the following statements relating to electrochemistry are correct?. An electrochemical cell can be created by placing metallic electrodes into an electrolyte where a chemical reaction either uses or generates an electric current.
