The unsaturated hydrocarbon butadiene dimerizes to 4-vinylcyclohexene. When data collected in studies of the kinetics of this reaction were plotted against reaction time, plots of [C4H6] or ln[C4H6] produced curved lines, but the plot of 1/[C4H6] was linear. What is the rate law for the reaction? How many half lives will it take for the [C4H6] to decrease to 3.1% of its original concentration? The relationship of [A]t/[A]o is 0.50n where n is the number of half lives.
