The kinetics have been investigated of the reaction of ethene with [PtCl4]2–, [PtCl3(OH2)]–, and [PtCl2(OH2)2] in equilibrium in water at 25.0 °C, giving second-order rate constants of (2.06 ± 0.06)× 10–3, (9.1 ± 1.1)× 10–3, and (8.3 ± 3.0)× 10–3 dm3 mol–1 s–1 respectively. The overall reaction is irreversible and the products are monoplatinum mono-olefin complexes such as [PtCl3(C2H4)]– and [PtCl2(C2H4)(OH2)]
动力学研究了乙烯与[PtCl 4 ] 2–,[PtCl 3(OH 2)] -和[PtCl 2(OH 2)2 ]在水中平衡时在25.0°C的反应,得到第二个阶数常数分别为(2.06±0.06)×10 –3,(9.1±1.1)×10 –3和(8.3±3.0)×10 –3 dm 3 mol –1 s –1。整个反应是不可逆的,产物是单铂单烯烃络合物,例如[PtCl 3(C 2 H 4)] –和[PtCl 2(C 2 H 4)(OH 2)]。已经研究了稳态条件假设的有效性,并在这种情况下是有道理的。
