Some reactions proceed through a chain mechanism involving radicals, which are highly reactive species with one or more unpaired electrons. The radicals are produced in initiation steps, through either thermal or photodissociation. Reactions in which the radical centre is transferred are called propagation steps. The radicals are lost in termination steps. Consider the following chain mechanism:(1) AH → A + H·(2) A → B· + C(3) AH + B· → A + D(4) A + B· → P(a) Identify the initiation, propagation, and termination steps.(b) Use the steady-state approximation to deduce that the decompositionof AH is f irst-order in AH.
The rate law v=(kr1[A][B])/(kr2 + kr3[B]1/2) was established in a series of experiments. Identify the conditions under which (i) an order with respect to A, (ii) an order with respect to B, and (iii) an overall order, can be assigned.
Consider the chemical reaction described by 2A(aq) ⇌ D(aq)with rate constants k1 and k-1. If the reaction is subject to a temperature jump, derive the equation for d[D]/dt in terms of a relaxation constant t.
