The following mechanism has been proposed for the decomposition of ozone in the atmosphere.Step 1 O3 O2 + OStep 2 O + O3 2O2 (the reverse reaction is negligibly slow)Use the steady state approximation, with O treated as the intermediate, to find an expression for the rate of decomposition of O3, i.e. –d(O3)/dt. (Note, do not set d(O3)/dt equal to zero). When step 2 is slow, the rate of decomposition of ozone reduces toa. k1[O3]b. k1k-1/ k2 [O2]c. k1k2[O3]^2 / k-1 [O2]d. k2[O3]Enter the letter of the correct selection.
