Final answer:
The back reactions to form ethene and water from ethanol involve energy transfer, with differences in the behavior of the conjugate bases impacting entropy.
Explanation:
Similarity: In both the back reaction to form ethene and water from ethanol, there is a transfer of energy during the process.
Difference: The main difference lies in how the negatively charged conjugate bases (ethoxide and acetate) behave and how they interact with the solvent, affecting the entropy of the system.
