Question
**Bond Dissociation Energy of CH₄**

The bond dissociation energy, in kilojoules (kJ), needed to break 4 bond(s) in 1 mole of CH₄ molecules is determined using the given data.

**Table of Bond Dissociation Energies (in kJ/mol):**

- **Single Bonds**
  - H-H: 432
  - C-H: 411
  - C-C: 346
  - C-N: 305
  - C-O: 358
  - N-H: 386
  - N-N: 163
  - N-O: 201
  - O-H: 459
  - O-O: 142

- **Multiple Bonds**
  - C=C: 602
  - C≡C: 835
  - C=N: 615
  - C≡N: 887
  - C=O: 799
  - C≡O: 1072
  - N=N: 494
  - N≡N: 942

**Note:** All values are in kJ/mol.

To calculate the total energy to break all C-H bonds in CH₄, multiply the C-H bond energy (411 kJ/mol) by 4, since there are four C-H bonds in methane.
