Transition energy estimation based on bond length

In summary, the conversation is about a student who encountered a question in a textbook and is seeking help because their calculated answer is significantly different from the solution answer. They used the energy formula for a particle in a box with n(Initial) = 22 and n(End) = 23, resulting in a calculated box length of 732 pm. The student's answer is 39.3 nm, while the answer book's answer is 239 nm. The student is then reminded that the forum rules require them to show their work before receiving help. The student later provides an edited image, rotated 90 degrees, cropped, and with enhanced contrast, in hopes of making it easier for helpers to read.

I come across this question in a textbook. Somehow my result is way off from the solution answer. I used the energy formula for particle in a box with n(Initial) = 22 and n(End) = 23, the calculated box length is 732 pm. I arrived at an answer of 39.3 nm. The answer from the answer book is but 239 nm. Thanks for the help

Our rules say that you must show us your work, not just your answer, before our helpers give help.

You're making it hard for would be helpers. Can you rotate that image 90 degrees, crop,it and enhance the contrast?

We are volunteers here. If a helper thinks your post is difficult, he/she can just skip,it.

1. What is transition energy estimation based on bond length?

Transition energy estimation based on bond length is a scientific method used to predict the energy required for a chemical bond to change from one state to another, such as breaking or forming a bond between two atoms. This method is based on the relationship between bond length and bond energy, and is often used in the field of chemistry.

2. How is bond length related to bond energy?

Bond length and bond energy are inversely related. This means that as the bond length decreases, the bond energy increases, and vice versa. This is because a shorter bond length indicates a stronger bond, meaning more energy is required to break it.

3. What factors influence the transition energy estimation based on bond length?

The main factors that influence transition energy estimation based on bond length include the types of atoms involved, the bond strength, and the electronic configuration of the atoms. Other factors such as temperature and pressure can also affect the bond length and therefore the transition energy.

4. How accurate is transition energy estimation based on bond length?

The accuracy of this method depends on the complexity of the chemical system being studied and the accuracy of the data used for bond length and bond energy. In general, this method is considered to be a good estimation, but it may not always provide an exact value.

5. Can transition energy estimation based on bond length be used for all chemical reactions?

No, this method is most commonly used for predicting the transition energy of simple chemical reactions involving covalent bonds. It may not be applicable for reactions involving ionic or metallic bonds, as these have different bond characteristics.
