What corresponds to the faster rate a mechanism with a small activation energy or one with a large activation energy?
A mechanism with a small activation energy corresponds to a faster rate of reaction. This is because lower activation energy means that more molecules have enough energy to overcome the energy barrier and react at a given temperature. In contrast, a mechanism with a large activation energy typically results in a slower reaction rate, as fewer molecules can achieve the necessary energy to initiate the reaction. Thus, lower activation energy leads to a higher reaction rate.

How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
Does a catalyst effect Ea?
Yes, a catalyst can lower the activation energy (Ea) of a reaction by providing an alternative reaction pathway that involves a lower activation energy. This allows the reaction to occur more easily and at a faster rate.
How does activation energy effect the progress of a reaction?
Activation energy is the minimum amount of energy required to initiate a chemical reaction. A lower activation energy means that more molecules have enough energy to react, leading to a faster reaction rate. Conversely, a higher activation energy requires more energy input and can slow down the reaction rate.
How does activation energy affect the progess of a reaction?
Activation energy is the minimum amount of energy required for a reaction to occur. A higher activation energy barrier means fewer molecules have enough energy to react, slowing down the reaction. Conversely, a lower activation energy barrier allows more molecules to react, leading to a faster reaction rate.
Do catalysts lower the activation energy of chemical reactions?
Yes, catalysts lower the activation energy of chemical reactions by providing an alternative reaction pathway that has a lower activation energy. This allows the reaction to proceed at a faster rate under milder conditions.

What kind of energy do enzymes reduce?
Enzymes reduce activation energy, which is the energy required to start a chemical reaction. By lowering the activation energy, enzymes make reactions occur more readily and at a faster pace.
How does activation energy affect the length of a reaction?
as activation energy decreases, reaction will finish faster (length of reaction decreases)
How does activation energy effect the progress of a reaction?
Activation energy is the minimum amount of energy required to initiate a chemical reaction. A lower activation energy means that more molecules have enough energy to react, leading to a faster reaction rate. Conversely, a higher activation energy requires more energy input and can slow down the reaction rate.
What is the significance of the activation energy curve in the context of chemical reactions?
The activation energy curve shows the energy needed to start a chemical reaction. It is significant because it determines the rate at which a reaction occurs. Higher activation energy means a slower reaction, while lower activation energy means a faster reaction.
What is the relationship between an energy diagram and activation energy in a chemical reaction?
An energy diagram shows the energy changes that occur during a chemical reaction. Activation energy is the minimum amount of energy required for a reaction to occur. In the energy diagram, the activation energy is the energy barrier that must be overcome for the reaction to proceed. A higher activation energy means a slower reaction, while a lower activation energy means a faster reaction.
How does activation energy affect the progess of a reaction?
Activation energy is the minimum amount of energy required for a reaction to occur. A higher activation energy barrier means fewer molecules have enough energy to react, slowing down the reaction.

What is the role of activation energy in inorganic chemistry?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. In inorganic chemistry, activation energy determines the rate at which reactions proceed. Higher activation energy results in slower reactions, while lower activation energy results in faster reactions. By understanding activation energy, chemists can optimize reaction conditions and develop more efficient processes.
What is activation energy and how does it relate to cell metabolism?
Activation energy is the energy required to initiate a chemical reaction. In cell metabolism, enzymes lower the activation energy needed for reactions to occur, allowing them to proceed at a faster rate. This enables biological processes to efficiently convert molecules into products such as energy or building blocks for the cell.
Is this statement true Catalysts make chemical reactions proceed faster by reducing the activation energy?
yes!. the way the reaction gets faster is because the catalyst absorbs the reactant particles on its surface and weakens their bonds. Reactants particles colliding with weaker bonds actually overcomes the activation energy faster as it is now lower. The only thing a catalyst changes in a chemical reaction is the activation energy, keeping in mind that the catalyst increases the rate of reaction in both forward and backward reaction.
