+To address issue https://github.com/ReactionMechanismGenerator/RMG-database/issues/353
+in which it is suggested this rule was auto-generated using poor thermochemistry,
+and ended up much too fast, we have replaced it with the previous value for this reaction,
+https://rmg.mit.edu/database/kinetics/families/R_Recombination/training/40/
+Apparently taken from entry: C9H7_19 + H_15 <=> indene_25
+from kinetics library: kislovB
+This is pretty much the collision limit. (10^13 cm3/mol/s)
