The following mechanism has been proposed for the reaction of NO with Br_(2) to from NOBr. NO(g)+Br_(2)hArrNOBr_(2)(g) NOBr_(2)(g)+NO(g)rarr2NOBr(g) If the second step is the rate determining step, the order of the reaction with respect to NO(g) is

The rate constant for the decompoistion of a certain reaction is described by the equation: log k(s^(-1)) = 14 - (1.25 xx 10^(4) K)/(T) A two-step mechanism has been suggested for the reaction of nitric oxide and bromine: NO(g) + Br_(2)(g) overset(k_(1))rarr NOBr_(2)(g) NOBr_(2)(g)+NO(g) overset(k_(2))rarr 2NOBr(g) The observed rate law is, rate = k[NO]^(2)[Br_(2)] . Hence, the rate-determining step is

Determining the overall reaction and the molecularity of an elementary reaction : The following two - step mechanism hqas proposed for the gas-phase decomposition of nitrous oxide (N_(2)O) : Step 1: N_(2)O(g)rarrN_(2)(g)+O(g) Step 2: N_(2)O(g)+O(g)rarrN_(2)(g)+O_(2)(g) (i) Write the chemical equation for the overall reaction (ii) Identify any reaction intermediates (iii) What is the molecularity of each of the elementary reactions ? (iv) What is the molecularity of the overvall reaction Strategy : The step-by -step pathway by which a reaction occurs is called its mechanism. Some reactions takes place in a single step, but most reactions occur in a series of elementary steps. To identify intermediates and molecularity, look at the indicidual steps
