2.18 Technique of flooding. The reaction of a chromium-pyrazine complex, Cr-Pz, with certain cobalt complexes has been studied in the presence of added Pz with both Pz and Co in large excess over Cr-Pz. The data follow first-order kinetics; each experiment defines a value of kapp. In series (A), [Co] = 2.50 x 10-3 and in (B), 1.25 x 10-3 M. Plots of 1/kapp against [Pz] are linear. In (A), kapp-1 = 3.1 + 3.2 x 103 [Pz] s, and in B, kapp-1 = 3.1 + 6.4 X 103 [Pz] s. That is, there is a common intercept but a different slope. Express kapp in terms of [Co] and [Pz]; write the differential rate equation.
-18. Technique of flooding. The reaction of a chromium-pyrazine complex, Cr-Pz, with certain cobalt complexes has been studied in the presence of added Pz with both Pz and Co in large excess over Cr-Pz. 27 The data follow first-order kinetics; each experiment defines a value of k. In series (A),[Co]=2.50103 and in (B),1.25103M. Plots of 1/k against [Pz] are linear. In (A),k1=3.1+3.2103[Pz]s, and in B, k1=3.1+6.4103[Pz]s. That is, there is a common intercept but a different slope. Express k in terms of [Co] and [Pz]; write the differential rate equationStep by Step Solution
