反應系 $[Ni(H_2O)_6]^{2+}+4CN^-{ ightleftharpoons}[Ni(CN)_4]^{2-}$를 Counductivity-meter를 이용해서 0.005% Gelatin 水溶額에서 反應速度論을 硏究하였다. $[Ni(CN)_4]^{2-}$와 [CN]$^-$의 反應으로 부터 $[Ni(CN)_4]^{2-}$ 生成速度는 $[Ni(H_2O)_6]^{2+}$에 대해서 1次, [CN]$^-$에 대해서 4次인 총괄反應이 5次로 進行됨을 알았으며, 또한 活性化 파라메타 ${Delta}H^{ eq}$ 와 ${Delta}S^{ eq}$는 각각 5.15kcal/mole , -35.07 e.u가 되었다. 그리고 이들의 資料로 부터 이 反應系의 타당한 生成메카니즘을 제안하였다.
Kinetics studies on the reaction system of $[Ni(H_2O)_6]^{2+}+4CN^-{ ightleftharpoons}[Ni(CN)_4]^{2-}$ have been carried out in 0.005% gelatin solution at $25^{circ}C$ by means of conductometry. The fifth-order kinetics were observed in the formation rate of $[Ni(CN)_4]^{2-}$ from the reaction of [Ni(H$_2O)_6]^{2+}$ and [CN]$^-$. The reaction was found first order in $[Ni(H_2O)_6]^{2+}$ and fourth order in [CN]$^-$. ${Delta}H^{ eq}$ and ${Delta}S^{ eq}$ were obtained the values of 5.15kcal/mole and -35.07 e.u., respectively. We have proposed the possible mechanism from the data obtained.
