$cis - [Cr(en)_2Cl_2]^+ $착물의 수화반응에 대한 연구를 전기전도도법에 의해. 온도는 $15^{circ}C{sim}30^{circ}C$에서 압력은 $1{sim}2000bar$의 범위에서 실시하였다. 반응속도는 온도가 증가함에 따라 증가하고, 압력이 증가하면 감소하였다. 활성화부피(${Delta}V^{ eq}$)는 $25^{circ}C$, 1bar에서 $1.82cm^2/mole$로 비교적 작은 양의 값을 나타내었으며, 이 값은 압력이 증가함에 따라 감소하고 온도 증가에 따라서는 증가하였다. 활성화엔트로피(${Delta}S^{ eq}$)$</TEX>는 $25^{circ}C$, 1bar에서 -9.019 eu로 작은 음의 값을 나타내었다. 활성화파라미터의 값으로부터 수화반응의 메카니즘은 교환해리(Id)메카니즘인 것으로 밝혀졌다
Aquation reaction kinetics of $[Cr(en)_2Cl_2]^+$complex was carried by the electric conductivity method. Its temperature range was $15^{circ}C$ to $30^{circ}C$ and pressure was varied up to 2,000 bars. The reaction rate was increased with increasing temperature, but was reversed to increasing pressure. The activation volume(${Delta}V^{ eq}$) was increased with increasing temperature and decreased with increasing pressure. At $25^{circ}C$ and 1 bar it was fairly small positive value, $1.82cm^2/mole$. Activation entropy change(${Delta}S^{ eq}$) $</TEX>was calculated as small negative value,-9.019 eu, at $25^{circ}C$ and 1bar. Referring to the thermodynamic parameters, it was estimated that aquation reaction was proceeded by the interchange-dissociation(Id) mechanism
