Describe the arrhenius theory
WebCollision Theory- According to the collision theory, the molecules of reactants are assumed to be hard spheres and the reactions are assumed to occur only when these spheres (molecules) collide with each other. … WebThe Arrhenius equation is k = Ae^(-Ea/RT), where A is the frequency or pre-exponential factor and e^(-Ea/RT) represents the fraction of collisions that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea) at temperature T.This equation can be used to understand how the rate of a …

WebMar 1, 2024 · The Arrhenius theory is limited because it only identifies acid-base reactions in water. The Bronsted-Lowry theory is a more inclusive definition, capable of describing acid-base behavior under a wider range … WebThe basic similarity between the Arrhenius and Bronsted-Lowry definitions are the production of the hydrogen ion (H+) and the hydroxide ion (OH-). Acids are known with respect to their ability to ...
WebA catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the … WebAccording to the Arrhenius theory, a substance which has a hydrogen atom and can easily give hydrogen ion or proton in its aqueous solution is called as Arrhenius acid. For example, when hydrochloric acid is dissolved in water, it forms chloride ion (Cl – ) and hydronium ion (H 3 O + ).
