NEET2005PhysicsNuclear PhysicsActual
Assertion : It is not possible to use ³⁵ Cl as the fuel for fusion energy. Reason : The binding energy of ³⁵ Cl is too small.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- BIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Correct answer
C. If assertion is true but reason is false
Step-by-step solution
The process of nuclear fusion can be explained with the help of concept of binding energy per nucleon of very light nuclei and the intermediate nuclei. Binding energy per nucleon of very light nuclei is less than that of intermediate nuclei. It means light nuclei are less stable than that of intermediate nuclei. As ³⁵ Cl has a large binding energy therefore it cannot be used as fuel for fusion energy.
