| ELECTRON TRANSFER REACTION OF [Co(N3)(NH3)5]2+ BY IRON(Ⅱ) IN WATER MIXED WITH N,N-DIMETHYLFORMAMIDE |
|
| 摘要: 研究了H2O-DMF馄合溶剂中[Co(N3)(NH3)5]2+被Fe(Ⅱ)还原的反应速度变化规律后,证实:当DMF的摩尔分数XDMF<0.3时,表观速度常数KaDD随着XDMF增大而增大;XDMF>0.3时,Kapp随着XDMF增大而减小;Kapp与[H+]有良好线性关系。 |

| Abstract: The kinetics of the reduction of the [Co(N3))(NH3)5]2+ by iron(Ⅱ) was investigated inmixed solvents of N,N-Dimethylformamide and water. The apparent rate constant,kapp substantially increases with an increase in the dimethylfor amide concentration range XDMF<0.3,but it decreases as XDMF mol fraction higher than Kapp is also dependent upon [H+]and in a linear relationship with [HH+]. |
