Answer to Question #286594 in General Chemistry for 15555

Question

What would happen to the cyclopentadiene (C5H6) yield if the following is done: increase the temperature, decrease pressure, and increase the volume at which the reaction occurs while decreasing hydrogen iodide (HI) concentration and adding argon gas?

I₂(g)+C₅H₈(g)⇆C₅H₆(g)+2 HI(g) ∆H°= 92.5kj

Answer 1

The volume will increase

The kinetic data of cyclopentadiene C5H6 oxidation reactions is significant for the construction of aromatics oxidation mechanism because cyclopentadiene C5H6 has been proved to be an important intermediate in the aromatics combustion. Kinetics for the elementary reactions on the potential energy surface (PES) relevant for the C5H6 + HO2 reaction are studied in this work
