Part III E and Equilibrium Constant A.1. Using the graph paper at the back of this manual, plot your results for Part III as Ecell versus logl/Ag']). Draw a "best-fit" straight line through your results and extrapolate (dashed line) to the x-axis where Ecell = 0. Attach this graph to your Postlab. (2 marks) 2. Indicate on your graph, the value of log Qcathode where Ecell = 0. Use this value to calculate (show your work on the graphy the corresponding (Ag ) at this point (1 mark) V-23 B. Using your value of [Ag*) obtained from Qcathode, calculate your experimental equilibrium constant K for the following reaction (see the procedure given in Outline of Measurements, Part III).
