Question

he average bond energy of the single covalent bond in H_(2) Is 436kJ/mol Which of the following statements is true? A 436 kJ are required to break all of the chemical bonds in 1molH_(2) B 435 kJ are released when all of the chemical bonds in 1 mo H_(2) are broken. C 436 kJ are required to break one H-H bond. D 436 kJ are released when one H-H bond forms.

Answer 1

The correct answer is C. 436 kJ are required to break one H-H bond.Explanation:The average bond energy of the single covalent bond in H2 is 436 kJ/mol. This means that 436 kJ of energy is required to break one H-H bond.Option A is incorrect because it states that 436 kJ are required to break all of the chemical bonds in 1 mol H2. This is not true because there is only one H-H bond in 1 mol H2.Option B is incorrect because it states that 435 kJ are released when all of the chemical bonds in 1 mol H2 are broken. This is not true because the bond energy is 436 kJ/mol, not 435 kJ/mol.Option D is incorrect because it states that 436 kJ are released when one H-H bond forms. This is not true because bond formation releases energy, not requires it.Therefore, the correct answer is C. 436 kJ are required to break one H-H bond.
