The decay of the organics was followed using a gas chromatograph with a flame ionization detector (GC-FID) and the rate constants were determined using a relative rate method with different reference compounds. Room temperature rate constants are found to be (in cm3 molecule-1 s-1):  k1(OH + CH2=CHC(O)OH ) = (1.75±
