Comparison of the effective first-order rate coefficients for syn-CH₃CHOO at 298 K.

Process	Assumed coreactant concentration/cm−3	Bimolecular rate coefficient/cm3 s−1	Effective first-order rate coefficient/s−1
Thermal decomposition	—	—	146 ± 31a
syn-CH3CHOO + H2O	3.8 × 1017 (50% RH)	<1 × 10−16,b	<38
syn-CH3CHOO + SO2	9 × 1011 (35 ppbv)	(2.4–2.9) × 10−11,c	22–26
