Question

Cyclopentene, C5H8, is a colorless liquid at room temperature that is used in the synthesis of plastics. When heated well above its boiling point, this compound decomposes to hydrogen gas and cyclopentadiene.

 

C5H8(g)⟶C5H6(g)+H2(g)

In three separate experiments, a sample of cyclopentene in a sealed vessel was heated to 825 K, and the initial pressure of cyclopentene (?=0 s) and final total pressure in the vessel (?=300 s) were recorded.

Experiment ?C5H8 (atm) at ?=0 s ?total (atm) at ?=300 s
1 121.1 191.2
2 142.4 224.8
3 166.1 262.2

Determine the rate constant for this reaction?
