- If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places.
- If there is no lower limit, check the "no" box.
*Options:*
- ☑️ yes, there is a minimum. \[ E^\circ_{\text{red}} = \] ⬜ V
- ⬜ no minimum
**2. Maximum Standard Reduction Potential**
*Question:*
Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have?
*Instructions:*
- If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places.
- If there is no upper limit, check the "no" box.
*Options:*
- ⬜ yes, there is a maximum. \[ E^\circ_{\text{red}} = \] ⬜ V
- ⬜ no maximum
**3. Writing a Balanced Equation**
*Task:*
By using the information in the ALEKS Data tab, write a balanced equation describing a half-reaction that could be used at the cathode of this cell.
