    • The observed second-order rate constants of the studied reaction are k2 = 1.66 ± 0.02 (35.0 °C), 2.53 ± 0.03 (45.0 °C), and 3.52 ± 0.03 × 10-5 M-1 s-1 (55.0 °C), and the activation parameters of ΔH? = 6.9 ± 0.3 kcal/mol and ΔS ? = -58 ± 1 eu are obtained.

    • Taking into account the value of kAn = 100 × 10-3 M-1 s-1 at 35.0 °C calculated by extrapolation in the Arrhenius plot (r = 0.999) with kinetic data: k2 = 117, 162, and 211 × 10-3 M-1 s-1 at 40.0, 50.0, and 60.0 °C, respectively, from ref 2l, the ratio of kPyr(35.0 °C)/kAn(35.0 °C) = (127× 10-3)/(100 × 10-3) = 1.27 is obtained.
