Part B: The Nernst Equation Write the Nernst equation? for the reaction Cu²* (ag) + Zn (s) → Zn2+ (ag) + Cu (s) Let activity of Cu²+ equal to 1 and change the activity of Zn?* such that Q is in the range – 0.001 to +0.001. Select different values of Q and for each calculate Ecell- Plot Ecell – Eell vs In Q. What is the effect of Q (that is the activity) on Ecell – Eell ? Is the effect the same at higher and lower values of Q? what is the largest value of the absolute difference between cell potential and standard cell potential, |Ecell – Eselll? What do you expect the graph will look like for different number of electron transferred (v )? And why?
