°C were analyzed in terms of the rate law to obtain the values of the rate constants (k1–k6). The activation parameters were obtained for the k1 paths of both arsonates and arsinates, which are the reaction between R′AsO32− or R′2AsO2− and water. It is noticeable that the values of the activation entropies of the arsonates were found to be negative, while those of the arsinate were found to be positive
在大于 6 的 pH 范围内测量胂酸烷基酯(甲基-、丁基-、己基-和苄基-)和胂酸二烷基酯(二甲基-和二丁基-)与溶剂
水的氧交换反应速率 (RS),并且在温度在 30 到 0 °C 之间。对于纵火犯,比率 (R) 由以下比率定律表示: R = k1[A2−] + k2[HA−] + k3[H2A] + k4[HA−]2 + k5[HA−][H2A] + k6[H2A]2,其中 A2-、HA- 和 H2A 分别表示 R'AsO32-、R'AsO3H- 和 R'AsO3H2(R' = 烷基)。对于
砷酸盐,R = k1[R'2AsO2−] + k2[R'AsO2H] (pH > 9)。根据速率定律分析 0 和 30 °C 时
砷酸盐的交换率,以获得速率常数 (k1-k6) 的值。获得了
砷酸盐和
砷酸盐的 k1 路径的活化参数,它们是 R'AsO32- 或 R'2AsO2- 与
水之间的反应。值得注意的
