a.) Write the net-ionic equation for the overall reaction that takes place as the cell operates. b.) Calculate the value of E° for the cell. c.) Calculate ΔG°, in kJ/molrxn, for the cell. d.) The following diagram on the left represents the copper nitrate solution in the half-cell before the galvanic cell starts to operate. In the following diagram on the right, draw a representation of the solution I'm the same half-cell after the galvanic cell has been operating for some time and is still producing a voltage. e.) Assume that the mass of the Cu electrode changes by x grams in a certain period of time. Write a mathematical expression for the change in mass of the Zn electrode during the same period of time. f.) For the standard cell, the Cu2+ half-cell was made with 1.0 L of 1.0 M Cu(NO3)22 and the Zn2+ half-cell was made with 1.0 L of 1.0 M Zn(NO3)2. The experiment was repeated, but this time the Cu2+ half-cell was made with 0.50 L of 2.0 M Cu(NO3)2 and the Zn2+ half-cell was made with 1.0 L of 1.0 M Zn(NO3)2. Is the cell potential for the nonstandard cell greater than, less than, or equal to the value calculated in part (b)? Justify your answer. g.) If the experiment is repeated with the Cu electrode replaced with a Cu electrode twice the mass, will the initial cell voltage be greater than, less than, or equal to the initial cell voltage in the original experiment? Justify your answer.
*I already did (a) and (b) just so you know. I just need help with the rest. If you can only help me with 3 of them, can you help me with (e), (f), and (g) please. Sorry it's a lot, but thank you! I really appreciate it.*
