View SolutionTeena and Neena while reading books on ozone depletion came across some information which is given below. Both chlorofluorocarbons (freons) and oxides of nitrogen can catalyse the destruction of ozone in the upper layer of the atmosphere. The activation energies of the reactions which cause ozone depletion are 2.1 kJ/mole in the presence of freons and 11.9 kJ/mole in the pressure of the oxides of nitrogen. Based on the above information, Teena and Neena had an argument. According to Teena, freons are more harmful. In Neena's opinion, the oxides of nitrogen cause more harm. Can you justify who is correct ?
