Significance of arrhenius equation
WebWhy is Arrhenius theory important? First of all, it was the first theory to produce comprehensive criteria for acids and bases, even though it had its faults.It was also the first theory on acids and bases that recognised the importance of solvents in neutralisation and the production of water during the reaction. WebNov 27, 2024 · Arrhenius came up with an equation that demonstrated that rate constants of different kinds of chemical reactions varied with temperature. This equation indicates a rate constant that has a proportional relationship with temperature. For example, as the rate constant increases, the temperature of the chemical reaction generally also increases.
