Arrhenius investigated the reaction rate of sucrose inversion by acids, highlighting the strong relationship between reaction speed and the electrical conductivity of the solution. He proposed that the reaction rate depends on the number of active ions, though this relationship was not strictly proportional. Experimental data supported the idea that reaction rates increase with temperature, following an exponential relationship. Arrhenius derived a formula for the temperature dependence of reaction rates, which was validated by multiple experiments. He also explored how neutral salts affect the reaction rate, finding that their addition can increase the reaction speed despite reducing the number of active ions. This was explained by the increased concentration of active sucrose molecules. Arrhenius further analyzed the effect of different acids on sucrose inversion, showing that the reaction rate is proportional to the concentration of hydrogen ions. He concluded that the active sucrose molecule is influenced by the presence of ions, and that the reaction rate depends on the concentration of active ions rather than the total number of ions. The study emphasized the importance of ion activity in determining reaction rates and provided a foundation for understanding the temperature dependence of chemical reactions.Arrhenius investigated the reaction rate of sucrose inversion by acids, highlighting the strong relationship between reaction speed and the electrical conductivity of the solution.
