Ch.16 kinetics problems

  1. 1. November 26, 2010 66. A + B gives AB Elementary step A + A gives C C + B gives BC Overall 2A + B gives C + BC 72. a) A + B + C gives D b) X and Y c) step 1 is bimolecular rate = k[A][B] step 2 is bimolecular rate = k[X][C] step 3 is unimolecular rate = k[Y] d) yes e) yes it's possible
  2. 2. November 26, 2010 73. a. ClO- + I- gives Cl- + IO- b.H2O, OH-, HIO, HClO c. step 1 is bimolecular rate = k[ClO-][H2O] step 2 is bimolecular rate = k[ I-][HClO] step 3 is bimolecular rate = k[OH-][HIO] d. slow step rate law is rate =k[ I-][HClO] this is not consistent with the proposed rate law. The HClO is an intermediate and should be replaced. From step 1, leaving out water, [HClO] = [ClO-]/[OH-]. Replacing [HClO] in the slow step rate law gives: rate = k[I-][ClO-]/[OH-]. This is not the observed rate law.
