Importance of arrhenius theory
WitrynaAdvantages of the Bronsted – Lowry theory: (a) It includes all substances described as acids and bases by Arrhenius. This theory explains the behavior of acids and bases in both aqueous and non-aqueous solvents. It can explain the fundamental character of substances like Na 2 CO 3 i.e. which do not surround OH– group and therefore were … Arrhenius argued that for reactants to transform into products, they must first acquire a minimum amount of energy, called the activation energy Ea. At an absolute temperature T, the fraction of molecules that have a kinetic energy greater than Ea can be calculated from statistical mechanics. The concept of activation energy explains the exponential nature of the relationship, and in one way or another, it is present in all kinetic theories.
