Chapter 12, Problem 4E

A study of the rate of dimerization of C₄H₆ gave the data shown in the table:

   $2{\text{C}}_4{\text{H}}_6\to {\text{C}}_8{\text{H}}_{12}$

(a) Determine the average rate of dimerization between 0 s and 1600 s, and between 1600 s and 3200 s.
(b) Estimate the instantaneous rate of dimerization at 3200 s from a graph of time versus [C₄H₆]. What are the units of this rate?
(c) Determine the average rate of formation of C₈H₁₂ at 1600 s and the instantaneous rate of formation at 3200 s from the rates found in parts (a) and (b).
