Suppose the decomposition of dinitrogen monoxide proceeds by the following mechanism:
step. elementary reaction. rate constant
1. n2o(g)=n2(g)+o(g). k1
2. n2o(g)+o(g)=n2(g)+o2(g). k2
suppose also k1<
write the balance chemical question for the overall chemical reaction:
write the experimental observable rate law for the overall chemical reaction. know your answer should not contain the concentrations of any intermediates.
express the rate constant k for the overall chemical reaction in terms of k1, k2 and if necessary the reconnaissance k -1 and k -2 for the reverse of the two elementary reactions in the mechanism.

Give the set of reactants (including an alkyl halide and a nucleophile) that could be used to synthesize the following ether: draw the molecules on the canvas by choosing buttons from the tools (for bonds and charges), atoms, and templates toolbars, including charges where needed. ch3ch2och2ch2chch3 | ch3
