Homework Answers
Answer is electrolytic cell because electrolytic cell use an external circuit to preform the reaction which is the condition for non spontaneous reactions. Spontaneous reaction occur due to itself no external energy is needed.

One difference between an electrolytic cell and a galvanic (voltaic) cell is the galvanic cell reaction is spontaneous and the electrolytic cell reaction is not spontaneous. galvanic cells last longer than electrolytic cells.` electrolytic cells produce more power than galvanic cells. electrolytic cells always require inert electrodes .electrons flow from the anode to the cathode in a galvanic cell and in the opposite direction in a voltaic cell.

Electrolytic cells use electricity to cause a nonspontaneous redox reaction to occur. An electrolytic cell is constructed using the following components: . a power source, such as a battery, • the substance that will undergo electrolysis, and • two inert electrodes (usually platinum), which serve as the electrical connection between the power source and the substance undergoing electrolysis. As with any cell, oxidation occurs at the anode and reduction occurs at the cathode. The oxidation of water, which produces oxygen...

In Part B we were going to construct concentration cells. In these galvanic cells, the driving force is the difference in concentration in the two half-cells. Write the anode and cathode reactions for a concentration cell which contains 0.1 M Cu2+ in one half-cell and 0.01 M Cu2+ in the other. (Be clear as to which [Cu2+] is being oxidized or reduced).
