A hypothetical reaction A_(2) + B_(2) rarr 2AB follows the mechanism as given below: A_(2) hArr A+A ("fast") A+B_(2) rarr AB+B (slow) A+B rarr AB (fast) The order of the overall reaction is

The rate and mechamical reaction are studied in chemical kinetics. The elementary reactions are single step reaction having no mechanism. The order of reaction and molecularity are same for elementary reactions. The rate of forward reaction aA + bBrarr cC+dD is given as: rate =((dx)/(dt))=-1/a(d[A])/(dt)=-1/b(d[B])/(dt)=1/c(d[C])/(dt)=1/d(d[D])/(dt) or expression can be written as : rate =K_(1)[A]^(a)[B]^(b)-K_(2)[C]^(c )[D]^(d) . At equilibrium, rate = 0 . The constants K, K_(1), K_(2) are rate constants of respective reaction. In case of reactions governed by two or more steps reaction mechanism, the rate is given by the slowest step of mechanism. For the reaction, 2NO+Br_(2) hArr 2NOBr , the mechanism is given in two steps: (1) NO+Br_(2) overset("fast")(hArr)NOBr_(2) (2) NOBr_(2)+NO overset("slow")(rarr)2NOBr The rate expression for the reaction is:

The reaction 2NO + Br_(2) to 2NOBr , obeys the following mechanism: NO + Br_(2) overset("fast")(hArr) NOBr_(2), NOBr_(2) + NO overset("Slow")(to) 2NOBr The rate expression of the above reaction can be written as

The reaction, 2NO+Br_(2)rarr 2NOBr , is supposed to follow the following mechanism, (i) NO+Br_(2) overset("fast")(hArr) NOBr_(2) (ii) NOBr_(2) +NO overset(slow)(rarr)2NOBr suggest the rate law expression.

The mechanism of the reaction 2NO + O_(2) rarr 2NO_(2) is NO + NO underset(k_(-1))overset(k_(1))hArr N_(2)O_(2) ("fast") N_(2)O_(2) + O_(2) overset(k_(2))rarr 2NO_(2) (slow) The rate constant of the reaction is
