1.	The reaction of ozone with oxygen atoms in the presence of chlorine atoms can occur by two step process shown below, O_(3)(g)+Cl(g) to O_(2)(g)+ClO(g)… (i) [K_(i)=5.2times10^(9) Lmol^(-1)s^(-1) ClO(g)+O_(2)(g) to O_(2)(g)+Cl(g)…. (ii) [K_(ii)=2.6times10^(10)lmol^(-1)s^(-1)] The closet rate constant for the overall reaction O_(3)(g)+O(g) to 2O_(2)(g) is:
Answer» `1.4times10^(20)lmol^(-1)s^(-1)` `3.1times10^(10)lmol^(-1)s^(-1)` `5.2times10^(9)lmol^(-1)s^(-1)` `2.6times10^(10)lmol^(-1)s^(-1)` Solution : On adding EQ. (i) and and eq.(ii) wer get `O_(3)(g)+O(g) to 2O_(2)(g)` Hence overall rate CONSTANT=`K_(i)K_(n)=5.2times10^(9)times2.6times10^(10)=1.4times10^(2)mol^(-1)Ls^(-1)`
