Homework Help: Reaction Stiochiometry Involving Gases

Posted by Kyle on Sunday, October 25, 2009 at 1:32pm.

Ozone is depleted in the stratosphere by chlorine from CF3Cl according to the following set of equations:

CF3Cl + UV Light ---> CF3 + Cl
Cl + O3 ---> ClO + O2
O3 + UV Light ---> O2 + O
ClO + O ----> Cl + O2

What total volume of ozone measured at a pressure of 25.0 mmHg and a temperature of 235 K can be destroyed when all of the chlorine from 15.5g of CF3Cl goes through ten cycles of the above reactions?

how many moles of CF3Cl are in 15.5 grams?

I appears to me that two moles of ozone per cycle are destroyed per one mole of CF3Cl
