Assignment: Electrode Potential
The chemistry of electrochemical cells involves redox reactions. In this
assignment, demonstrate your understanding of the electrode potential and half
reactions by completing a problem set.
Instructions
Your task is to complete the questions in the problem set. Please note that you
must include units throughout all of your calculations and provide your answer in
scientific notation to the correct number of significant digits.
Questions
1. For each of the cell diagrams, provide the following information:
The E
(1 mark each)
The two redox half reactions (oxidation and reduction) (1 marks each)
The balanced net ionic equation (1 mark each)
Whether the reaction is spontaneous (1 mark each)
