Explanation:
395.2kcal
Explanation:
Given parameters:
Energy required to break one C-H bond = 98.8kcals
Unknown:
Energy required to break methane = ?
Solution:
The bond dissociation energy is the heat energy absorbed in breaking a covalent bond in the gas phase to its constituents elements.
Solving
CH₄ has 4 C-H bonds
To break 1 C-H bond, 98.8kcals of energy was used,
To break 4 of the bonds; 4 x 98.8kcals will be used = 395.2kcal
