The bond energy of H2 is 104.3 kcal/mol. It means that
- 104.3 kcal heat is needed to break one bond to form two
atoms - 104.3 kcal is required to break 6.02 × 1023 molecules
into 1.2406 × 1024 atoms of hydrogen - 104.3 kcal is required to break 3.015 × 1023 hydrogen
molecules to 6.02 × 1023 hydrogen atoms - none of these
Answer
(B) 104.3 kcal is required to break 6.02 × 10 23 molecules into 1.2406 × 10 24 atoms of hydrogen
