Cyclopentadiene (C5H6) reacts with itself to form dicyclopentadiene (C10H12). A 0.0400 M solution of C5H6 was monitored as a function of time as the reaction 2 C5H6 → C10H12 proceeded. The following data were collected:
Time (s) [C5H6] (M)
0.0........................0.0400
50.0......................0.0300
100.0.....................0.0240
150.0.....................0.0200
200.0......................0.0174
Plot [C5H6] versus time, ln [C5H6] versus time, and versus time. What is the order of the reaction? What is the value of the rate constant?
