Question

22. Assume that each of the reactions below is an elementaryreaction. Identify each reaction as univolecular, bimolecular, ortermoleular, an write a rate expression for each. a. N2O4(g) 2NO2(g) b.2NO2(g)N2O4(g) c.CO(g)+ Cl2(g)COCl(g)+Cl(g) 22. Assume that each of the reactions below is an elementaryreaction. Identify each reaction as univolecular, bimolecular, ortermoleular, an write a rate expression for each. a. N2O4(g) 2NO2(g) b.2NO2(g)N2O4(g) c.CO(g)+ Cl2(g)COCl(g)+Cl(g) b.2NO2(g)N2O4(g) c.CO(g)+ Cl2(g)COCl(g)+Cl(g)

Explanation / Answer

To determine molecularity, count up the coefficient of thereactants. a. 1 N2O4 -> unimolecular b. 2 NO2 -> bi molecular c. 1 CO + 1 Cl2 -> 2 total -> bimolecular Rate law: only the reactants, the coefficient represents thepower. a. rate = k[N2O4] b. rate = k[NO2]2c. rate = k[CO][Cl2]
