Question

In an electrochemical cell, the potential difference between two electrodes under standard conditions is know as the standard cell potential (E degree cell). The standard cell potential can be used to idential the overall tendency of a redox reaction to occur spontaneously. The spontaneity of a reaction is identified using tyhe Gibbs free energy Delta G degree, Delta G degree is related to E degree cell, E degree cell and Delta G degree are also related to equilibrium constant Keq of the reaction. Select the image to explore the activity that shows how E degree cell, Keq, and Delta G degree are related to each other. In the activity, ypou should see a triangle, whose three vertices represent Keq, E degree cell, and Delta G degree. Tou can select two vertices and determine the relation between them. You can then reset the activity and select the next two quantities. Constant The following values may be useful when solving this tutorial. Constant Value E degree Cu 0.337 V E degree Co -0.277 V R 8.314 J.mol-1.K-1 F 96,485 C / mol T 298 K In the activity, click on the E degree cell and Keq quantities to observe how they are related. Use relation to calculate Keq for the following redox reaction that occurs in an elecrochemical cell having two electrodes: a cathode and an anode. The two half-rections that occur in the cell are Cu2+(aq) + 2e- rightarrow Cu(s) and Co(s) rightarrowCo2+(aq) + 2e- The net reaction is Cu2+(aq) + Co(s) rightarrow Cu(s) + Co2+(aq) Use the given standerd reduction potentials in your calculation as appropriate. Express your answer numerically to three significant figures. You did not open hints for this part. This question will be shown after you complete previous question(s).
