How is the energy change (∆E) in the case of an absorption spectrum, where n f > n i ?
Options
- A∆E is positive, indicating energy is released.
- B∆E is negative, indicating energy is absorbed.
- C∆E is zero, indicating no energy change.
- D∆E is unpredictable in this case.
Correct answer
B. ∆E is negative, indicating energy is absorbed.
Step-by-step solution
In the case of an absorption spectrum, where n f > n i , ∆E is negative, indicating that energy is absorbed.
