What is the solution to A-E? The gas-phase conversion of 1,3 butadiene to 1,5-cy

Question

What is the solution to A-E? The gas-phase conversion of 1,3 butadiene to 1,5-cyclooctadiene, 2C_4 H_6 rightarrow C_8 H_12 was studied, providing data for the plot shown below, of 1/[butadiene] versus time. a. Explain how this plot confirms that the reaction is second order. b. Calculate the second-order rate constant, k. Include units. c. Determine the initial concentration of 1,3-butadiene in this experiment. d. Determine the concentration at 1500 sec of 1,3-butadiene in this experiment. e. What is the half-life concentration?

Explanation / Answer

A. Since here the concentration increasing linearly with time and giving straight line.

B. For II second order reaction rate constant = 1/t .x/ a.(a-x).

Units : dm3 /mol/sec

C. O.025 M

D. 0.01M

E. 0.0125M
