Cyclopropane isomerizes into propene when heated to 500°C in the gas phase. The extent of conversion was followed by gas chromatography by allowing the reaction to proceed for a time with various initial pressures: Po/Torr t/s 200 200 400 400 600 600 100 200 100 200 100 200 pr 186 173 373 347 559 520 where p, is the initial pressure of cyclopropane and pr the pressure of cyclopropane after t seconds. What is the order of the reaction and the value of the rate constant for the reaction under these conditions? (NOTE: px (nx/V)*RT = [X]*RT, so you can use pressure-rather than concentration-in the rate law equations.

Only typed solution

Using the calculated results in the picture attached, starting at 15 minutes, calculate the rate constants, k (last column in the data sheet). Then calculate the average value of k. Use the following equation to help calculate: ln (a/a0) = -kt
