Why rate constant decrease when activation increase in arrhenius equation?

The rate constant in the Arrhenius equation decreases as the activation energy increases because a higher activation energy means that fewer molecules possess the required energy to overcome the energy barrier and react. This results in a lower frequency of successful collisions between reacting molecules, leading to a decrease in the rate constant.


According to the Arrhenius equation changing which factors will affect the rate constant?

The factors that can affect the rate constant in the Arrhenius equation are temperature and activation energy. Increasing the temperature will increase the rate constant, as reactions occur more rapidly at higher temperatures. Similarly, changing the activation energy required for the reaction will also impact the rate constant.


How does activation energy affect chemical reactions?

The Arrhenius equation is: Ea = -RT ln(k/A) where Ea - activation energy R - universal gas constant ln - logarithm k - speed constant T - temperature in kelvins


Will affect the rate of the constant according to the Arrhenius equation changing which factors?

The rate constant in the Arrhenius equation is impacted by temperature and activation energy. Increasing temperature generally increases the rate constant as molecules have more energy to overcome activation barriers. Similarly, lowering the activation energy required can lead to a higher rate constant.


What is the relationship between the rate constant of a reaction and the activation energy of the reaction?

The rate constant of a reaction is directly related to the activation energy of the reaction. A higher activation energy typically results in a lower rate constant, meaning the reaction proceeds more slowly. Conversely, a lower activation energy usually leads to a higher rate constant, indicating a faster reaction.


Does a catalyst decrease or increase the activation energy required?

The catalyst decrease the needed activation energy.


When the catalyst bonds with the activated complex what is its effect on the activation energy and the rate and nbsp?

The activation energy is lower and the reaction rate increase.


Can a reaction have zero activation energy?

No, all reactions require some activation energy to proceed, even if it is very small. Activation energy is the minimum amount of energy required for reactant molecules to transform into product molecules.


How does concentration affect activation energy?

Because the concentration is directly proportional to the rate of reaction (the rate will increase but k will remain the same), with an increase in concentration the activation energy will stay because the activation energy does not account for the concentration.


The smallest amount of energy needed to start a chemical reaction is called?

Technically, it isn't "heat" that makes a chemical reaction happen. "Heat" is merely the flow of energy from one place to another. It is the energy itself that causes a reaction to occur. As an increase in temperature occurs, there is an increase in the energy in a group of molecules by making them mover around faster and bum into each other more. This energy is called "Activation energy", and is defined as the amount of energy required to make the reaction start and carry on spontaneously. Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy. With that being said, activation energy is the answer


Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?

Enzymes decrease the activation energy of a chemical reaction. They do this by providing an alternative pathway with a lower activation energy that allows the reaction to proceed more rapidly.


Do catalysts decrease or increase energy required to begin a reaction?

Catalysts decrease activation energy.
