Please only help with parts a and b. Thank you.

a) Derive a rate equation for the decomposition of ozone assuming step 1 is fast and reversible

b) Derive a rate equation for the decomposition of ozone using the steady state approximation.

15.23 The rate law for the decomposition of ozone to molecular oxygen 2O3(g)3O2(g) is rate=k[O2][O3]2 The mechanism proposed for this process is O3k1k1O+O2O+O3k22O2 Derive the rate law from these elementary steps. Clearly state the assumptions you use in the derivation. Explain why the rate decreases with increasing O2 concentration
