Figure 4.

(a) Arrhenius plots describing the temperature-dependence of first-order rate constants of HFPO-DA, PEPA, and PMPA in acetonitrile (ACN) at three temperatures [cold (3.4°C), room (20.2°C), and hot (32.4°C)]; and (b) the Arrhenius plot of the first-order rate constants of HFPODA in ACN, acetone, and dimethyl sulfoxide (DMSO). The first-order rate constants at different temperatures are given in Table S11. Temperature was recorded at least four times during the test and average temperature was reported. Experiment was not conducted at 3.4°C in DMSO due to the high melting point of DMSO (19°C). See Figure S1 for compound structures.
