Integrated Rate Law

Q. Butadiene, C4H6, may react in a second-order reaction to form 1,5-cyclooctadiene, C8H12, as follows. 2 C4H6(g) -> C8H12(g) At 600 K, this reaction has a rate constant of 1.9 × 10-3 M-1 s-1. If a 5.00-L sealed vessel is filled with 0.031 mol/L of butadiene at 600 K and the above reaction is initiated, how long (in hr) will it take for the total pressure inside the vessel to fall to 0.90 atm?
