When a slow dry current(stream) of oxygen is passed through silent electrical discharge, oxygen gets converted to ozone(about 10%). The product is known as ozonised oxygen.
What is silent electric discharge?
The silent electric discharge is a special type of electricity which has no sparks and creates very low amount of heat energy. … That’s why, silent electric discharge is used to prepare ozone in order to maintain the stability of the ozone molecules and to prevent the dissociation into oxygen molecules.
Which one is obtained by passing silent electric discharge at room temperature?
Ozone is prepared by passing silent electric discharge through oxygen.
When a slow dry stream of oxygen is passed through a silent?
When a slow dry stream of oxygen is passed through a silent electrical discharge, conversion of oxygen to ozone (10%) occurs. The product is known as ozonised oxygen.
What happens when silent electric discharge is passed on oxygen gas?
When a silent electric discharge is passed through dry oxygen, ozone is formed. … The reaction is initiated by a sparkless or silent electric discharge, to produce less heat, as ozone is prone to decomposing back into oxygen with an increase in temperature (Le Chatelier’s Principle).
What do you mean by electric discharge?
An electric discharge is the release and transmission of electricity in an applied electric field through a medium such as a gas. … As the charge on these particles builds up, the result is the often-spectacular discharge of electricity known as lightning.
Is the formation of ozone endothermic or exothermic?
These single atoms are then able to react with other oxygen molecules, forming ozone. This process is an endothermic reaction, meaning it needs to absorb energy (in this case the UV radiation) in order to occur.
How is ozone prepared by Siemen’s Ozoniser?
Siemens ozonizer: On a large scale, 03 is prepared by passing silent electric discharge through the air. … In order to obtain pure ozone from ozonised oxygen, it is cooled with liquid air when ozone (b.pt. 160.6 K) condenses as a deep blue liquid while oxygen (b.pt. 90 K) remains as a gas at this temperature.
