Abstract	VO2+와 [Mo3O4(H2O)9]4+의 산화반응에 대한 속도론을 25℃에서 분광광도법으로 연구하였다. 과량의 VO2+에서 [Mo3O4(H2O)9]4+의 산화반응은 MoⅣ3 + 6VⅤ ↔ 3MoⅥ + 6V^Ⅳ이다. 반응에 대한 관찰된 속도상수, kobs는 수소이온과 VO2+에 의존한다. [Mo3O4(H2O)9]4+와 VO2+의 산화-환원반응에 대한 상세한 메카니즘이 제시되며 이에 대하여 논의된다. The kinetics of the reaction of [Mo3O4(H2O)9]4+ with VO2+ have been studied at 25℃ by spectrophotometric method. With VO2+ in excess, the [Mo3O4(H2O)9]4+ reaction can be expressed as MoⅣ3 + 6VⅤ ↔ 3MoⅥ + 6VⅣ. Observed rate constants for the reaction are dependent on [H+] and [VO2+]. Mechanism for the redox of [Mo3O4(H2O)9]4+ and VO2+ is proposed and discussed.
