reactiion of sulfur and ozone

smartgene - 24-8-2016 at 07:10

hey I was wondering if you react ozone with dry sulfur will it form sulfur dioxide without combustion? I understand carbon reacts with ozone at room temperature to form carbon dioxide. So sulfur should react the same. Can someone answer this question.

Without knowing where you read that and the context in which it was said, I suspect that what was probably meant is that the reaction begins spontaneously when the reactions are brought into contact even at room temperature. After that point, the reaction does not necessarily remain at room temperature. Both reactions (carbon + ozone and sulfur + ozone) are exothermic, ie they release heat, and quite a bit of it. In fact more than the amount of heat you would get from the combustion of these fuels with oxygen.

Do you have to burned it for the reaction to start or it happens on its on

O3 being endothermic is also explosive if too hot and above a certain concentration.
2 O3 --> 3 O2 + heat

I wouldn't be surprised if the ozone further oxidized the sulfur dioxide to sulfur trioxide. (SO2 + O3 -> SO3 + O2)
