Question
Chlorination of methane involves three steps: chain-initiating, chain-propagating and chain-terminating.
When oxygen is passed through the reaction mixture, chlorination of methane slows down temporarily
Although chlorination of methane is an exothermic, the reaction requires high temperature because
- Activation energy is low
- heat of reaction is negative
- Chain-initiating step is endothermic
- Chain-terminating step is endothermic
The correct answer is: Chain-initiating step is endothermic
