2. The physical mechanism involved in elementary reactions was given as: A+ A → A* + A activation by binary collisions A* + A k_1 A + A deactivation by binary collisions A* + bA k2 products reaction step where b = 0 for unimolecular reaction steps b = 1 for bimolecular reaction steps b = 2 for termolecular reaction steps. 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.
