Figure 3: Kinetic data.

Time interval=50 ms. y Axis of Fig. 3a and Fig. 3c represent the absorbance at 630 nm. (a) [TBPH] and [Mn(TPP)Cl] were 2 × 10−2 and 6.7 × 10−6 M, respectively. [ArIO] was 2.5 × 10−4, 5 × 10−4, 7.5 × 10−4, 1 × 10−3 and 1.5 × 10−3 M, respectively. (b) First-order dependence on [ArIO]. (c) [ArIO] and [Mn(TPP)Cl] were 5 × 10−4 and 6.7 × 10−6, respectively. [TBPH] was 1 × 10−2, 2 × 10−2, 3 × 10−2 and 4 × 10−2 M, respectively. (d) Zero-order dependence on [TBPH].
