A catalyst speeds up a chemical reaction by providing an alternative pathway with a lower activation energy, allowing reactants to convert to products more easily. This acceleration increases the rate of reaction, enabling more collisions between reactant molecules to occur in a given time frame. Importantly, a catalyst is not consumed in the reaction, allowing it to facilitate multiple reaction cycles without being depleted.
What else can I help you with?
Would a catalyst cause an endothermic reaction to become exothermic?
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
Which will cause an increase in the reaction rate between molecules?
An increase in the reaction rate between molecules can be caused by several factors, including raising the temperature, which provides more energy to the molecules and increases their kinetic energy. Increasing the concentration of reactants can also enhance the reaction rate by allowing more frequent collisions between molecules. Additionally, the presence of a catalyst can accelerate the reaction without being consumed, lowering the activation energy required for the reaction to occur.
Do catalyst increase equilibrium constant?
No they do not. A catalyst is a thing (atom, molecule, element, etc.) that speeds up a chem. rxn by lowering the activation energy without being altered itself. So it only cause the reaction to occur faster, but will not have any affect on the equilibrium. Also, since the catalyst is not altered, it should 'come out' exactly as it 'went in.'
What action would cause the greatest increase in the speed of a chemical?
The greatest increase in the speed of a chemical reaction can be achieved by increasing the temperature. Higher temperatures provide reactant molecules with more kinetic energy, leading to more frequent and energetic collisions. Additionally, increasing the concentration of reactants or utilizing a catalyst can further enhance reaction speed, but temperature typically has the most significant effect.
Why is an enzyme considered a catalyst?
An enzyme is referred to as a catalyst as it sets off the digestive process beginning with amylase in the mouth which is produced by the salivary glands (...and followed by all the other enzymes that are mixed with the food along the alimentary canal)
What are two variables that would cause a chemical reaction to have a fast reaction rate?
Increased concentration, increased temperature, and a catalyst will all increase reaction rates relative to what they normally are. Some reactions however will still be slow even with the change in these variables.
What is the effect of a catalyst on a chemical reaction?
To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.
Would a catalyst cause an endothermic reaction to become exothermic?
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
Which methods will usually cause a reaction to speed up?
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.

How does a catalyst change the rate of a chemical reaction?
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
How does temperature increase cause the rate of a reaction to increase?
It increases the kinetic energy of the molecules (APEX)
What does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
What action would cause the greatest increase in the speed of a chemical?
The greatest increase in the speed of a chemical reaction can be achieved by increasing the temperature. Higher temperatures provide reactant molecules with more kinetic energy, leading to more frequent and energetic collisions. Additionally, increasing the concentration of reactants or utilizing a catalyst can further enhance reaction speed, but temperature typically has the most significant effect.
How does temperature increase cause the rate of reaction to increase?
The movement of molecules and collisions are increased at high temperature.
Why do tablets dissolve at differend speeds with differend temps of water?
First of all, I want to explain that the speed of reaction depends on several factors. They are: - Availability of a catalyst -Temperature of reactants -Pressure of the system -Surface area. If you increase the temperature, the speed of reaction will be higher. This is because more water molecules have more sufficient energy to cause a reaction whenever they react with the tablets.
