Title: How does the pressure affect homolysis?
Post by: Bolaf7654ggsf on March 04, 2021, 10:32:51 AM
I would like to know if high pressure is good for homolysis.

Acording to chemical balance rules, if you making two substances from one (decomposition) (you have one mole of substance, and after the reaction you have two) high pressure is bad, but can we apply this on radicals? If so, low pressure is good for homolysis.

But

I consider second option - like in pressure cooker the boiling point is lower when pressure is high - so I quess, that if you increase pressure, lower temperature is needed for homolysis.

I cannot figure out which of theese options is correct, can you help me?

Thanks

Not a very precise statement. Imagine the thermal decomposition of CS2 or HgO.
