Final answer:
Five steps to solve an electrochemical cell question on the MCAT include writing the cell's overall reaction, determining electron transfer, calculating voltage with the Nernst equation, comparing electrolytic and galvanic cells, and performing stoichiometric calculations for electrolytic processes.
Step-by-step explanation:
To solve an electrochemical cell question on the MCAT, you should follow these general steps:
- Write the overall reaction that occurs in the cell.
- Determine the number of electrons transferred in the reaction.
- Use the Nernst equation to calculate the voltage of the cell.
- Compare the operation of electrolytic cells with that of galvanic cells.
- Perform stoichiometric calculations for electrolytic processes, which involve writing the redox half reactions, determining the required voltage for electrolysis and balancing the charge with the appropriate ions.
Specific to the MCAT, these steps might involve understanding the underlying chemistry concepts, applying them to solve the question, and possibly comparing and contrasting different types of cells. For example, when dealing with electrolysis, you might be asked about the half reactions for a particular element and what voltage would be necessary for electroplating a specific metal.
