The RMG rules kinetics guess for this reaction is not good: + = +

It has a negative barrier and large temperature exponent.

It looks like it was copied into the database as a training reaction (training reaction number 450) based on an old rate rule for the propane (primary) radical and this is a secondary butane.

Here's the long description: Average of [ROOH_pri;C_rad/H/Cs\H3/Cs\H3] Estimated using an average for rate rule [ROOH_pri;C_rad/H/NonDeC] Euclidian distance = 0 family: H_Abstraction
