What does the general trend towards less negative Eo values across the series indicate?

Options

  1. AIncreasing ionization enthalpies
  2. BIncreasing hydration enthalpies
  3. CIncreasing reduction potential
  4. DDecreasing ionization enthalpies

Correct answer

D. Decreasing ionization enthalpies

Step-by-step solution

The general trend towards less negative Eo values across the series is related to the general increase in the sum of the first and second ionization enthalpies.
