In an electrochemical cell, the potential difference between two electrodes under standard conditions is known as the standard cell potential (El). The standard cell potential can be used to identify the overall tendency of a redox reaction to occur spontaneously. The spontaneity of a reaction is identified using the Gibbs free energy AG". AG" is related to EE and AG are also related to equilibrium constant Keq of the reaction. Select the image to explore the activity that shows how E Keq, and AG are related to each other. AG Keq E cell In the activity, you should see a triangle, whose three vertices represent Keq Elland AG. You can select two vertices and determine the relation between them. You can then reset the activity and select the next two quantities. Constants The following values may be useful when solving this tutorial. Part A and The net reaction is Constant E E LIVE ΑΣΦΗΚΑ → C In the activity, click on the Elland Keq quantities to observe how they are related. Use this relation to calculate Ke for the following redox reaction that occurs in an electrochemical cell having two electrodes: a cathode and an anode. The two half-reactions that occur in the cell are Cu²+ (aq) +2e →Cu(s) Use the given standard reduction potentials in your calculation as appropriate. Express your answer numerically to three significant figures. ▸ View Available Hint(s) ?
