General Treatment for Solving Steady States

Although each mechanism requires an individual solution, a general treatment for 

There are other special procedures that are applicable to chain reactions only. These are given in Chapter 6. 

Question. In Chapter 1, the physical mechanism involved in elementary reactions was given as 

A + A — A + A deactivation by binary collisions A + bA — products reaction step 

Carry out a steady state analysis to show that unimolecular reactions are first order at high pressures, moving to second order at low pressures. State the rate-determining steps in each region. In contrast, show that bimolecular reactions are second order at all pressures.
