Answer 2

Hey dear,

● Answer -
- Conversion of oxygen to ozone takes place as follows -
3O2 + electricity ---> 2O3
- This is an endothermic reaction.
- Formation of products is favoured by rise in temperature.
- Sparkless electrical current produces less heat than that of sparkling current.
- Thus, silent electric current is passed through oxygen to form ozone.
