Radical reactions are responsible for the catalysed breakdown of the ozone layer.

The overall equation is shown below:

2O3→3O2
ΔrH=-284kJmol-1
The molar gas volume in the ozone layer is approximately 2.5m3
mol-1
What is the energy release, in kJ, during the breakdown of 1.0m
3
of ozone in the ozone layer?

Have you figured it out I'm curious lol

I'm thinking maybe you would scale it out if 2.5m3 is 284kj maybe to get in 1m3 its 284/2.5
I doubt that's right lol

I’m thinking because u have the gas constant as 2.5 instead of normally 24 and u already have the concentration and volume, you do 1/2.5 x -284?

From what I think, because the molar gas volume is 2.5m3 per mole and there are 2 moles of ozone being broken down, if you do 2 times 2.5, this gives 5. So instead of 284 divided by 2.5 it would be 284 divided by 5 because 2 moles of ozone is broken down and 2.5m3mol-1 only applies to one mole.
