Lindemann proposed the following detailed mechanism for gas phase isomerization, the reaction is



In the above scheme, A is a molecule that has enough vibrational energy to decompose or isomerise. The Lindemann mechanism is followed by most of gas phase decomposition or isomerization reaction.

For the overall unimolecular isomerization of cyclopropane to propylene at , the values of versus concentration is as follows.

|M|kunit |1M|1137.5 |2M|1131.25in s1



As per Lindemann mechanism kunit is
