Catalysts lower the activation energy required for a chemical reaction, allowing reactants to convert into products more easily and quickly. They provide an alternative reaction pathway that requires less energy, but they do not alter the overall energy of the reactants or products. By facilitating the reaction, catalysts increase the reaction rate without being consumed in the process.

How do catalyst affect the energy reactions?
Catalysts doesn't affect the energy of reactions
Why are catalysts spread out in a reaction?
Catalysts are chemicals that alter the rate of a chemical reaction without being chemically changed themselves . However to alter the rate of the reaction , the catalysts need to come in contact with the reactant particles. Spreading out the catalyst increases its surface area , hence increases the chances of coming in contact with the reactant particles . So they are able to provide the reactant particles an alternative route with a lower activation energy for the reactant particles to collide and form the product .
How is a catalysts different from a reactant?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a reactant is a substance that participates in a chemical reaction and is consumed. Essentially, a catalyst speeds up a reaction without being changed itself, while a reactant is consumed during the reaction.
Can a catalyst change the orientation of a reactant collision?
No, a catalyst cannot change the orientation of a reactant collision. Catalysts work by providing an alternate reaction pathway with lower activation energy, but they do not influence the orientation of reactant collisions. The orientation of reactant collisions is determined by the relative positions and orientations of the reacting molecules.
How do catalysts alter a reaction?
Catalysts lower the activation energy required for a reaction to occur, making the reaction happen faster. They do this by providing an alternative pathway with a lower activation energy, allowing more reactant molecules to overcome the energy barrier and participate in the reaction. The catalyst itself is not consumed or changed during the reaction.

How is a catalysts different from a reactant?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a reactant is a substance that participates in a chemical reaction and is consumed. Essentially, a catalyst speeds up a reaction without being changed itself, while a reactant is consumed during the reaction.
How do catalyst affect the energy of reaction?
Catalysts greatly reduce the amount of activation energy needed to begin a reaction.
The speed at which a reactant will change to a product is proportional to its?
The speed at which a reactant will change to a product is proportional to its concentration. This relationship is described by the rate law of the reaction. Changes in other factors, such as temperature and the presence of catalysts, can also affect the reaction rate.
Can a catalyst change the orientation of a reactant collision?
No, a catalyst cannot change the orientation of a reactant collision. Catalysts work by providing an alternate reaction pathway with lower activation energy, but they do not influence the orientation of reactant collisions. The orientation of reactant collisions is determined by the relative positions and orientations of the reacting molecules.
What catalysts the amount of activation energy needed?
Using catalysts the activation energy is lowered.
How do catalysts alter a reaction?
Catalysts lower the activation energy required for a reaction to occur, making the reaction happen faster. They do this by providing an alternative pathway with a lower activation energy, allowing more reactant molecules to overcome the energy barrier and participate in the reaction. The catalyst itself is not consumed or changed during the reaction.
Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
Are catalysts included in rate laws and how do they affect the overall reaction rate?
Catalysts are not included in rate laws because they do not affect the overall reaction rate. Instead, catalysts speed up the reaction by providing an alternative pathway with lower activation energy, allowing the reaction to occur faster without being consumed in the process.
How do catalysts affect energy of reactions?
Catalysts lower the activation energy required for a reaction to take place by providing an alternative reaction pathway. This allows the reaction to proceed more quickly and with less energy input. The overall energy change of the reaction remains the same, but the rate of the reaction is increased.
