Question

4.5 eV is the required energy to beak one H-H bond. a) What is the nature of bonding in Hz. b) Calculate this energy in kJ/ k mol

Answer 1

The nature of bonding in H₂ molecule is covalent. The energy required to break one H-H bond is 4.5 eV, and this is equivalent to 435.178 kJ/kmol.

Step-by-step explanation:

The required energy to break one H-H bond is 4.5 eV.

a) Hydrogen gas (H₂) consists of two hydrogen atoms bonded together. Since each H-H bond requires 4.5 eV of energy to break, the nature of bonding in H₂ is a covalent bond.

b) To calculate the energy in kJ/kmol, we need to convert eV to kJ/mol. By using the conversion factor 1 eV = 96.485 kJ/mol, we can calculate that 4.5 eV is equal to 435.178 kJ/kmol.
