内容記述 |
In general, most chemical reactions are accelerated at higher temperature, while reactions of which activation energy is negative are accelerated at lower temperature. The reaction rates, however, become much slower in the ice phase because molecule cannot move easily. It was found that a few reactions of which activation energies were positive were accelerated in freezing aqueous solution. The reaction rates in the freezing process were 10 to (10)^5 times faster than those in solution at 25℃. The reaction occurred faster at faster freezing rate. Further, the reaction by freezing did not accelerate when the solution was frozen while stirring. It is proposed that the acceleration effect was based on the electrostatic concentrarion effect caused by ion separation. |
