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.
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 concentration increase would cause a tenfold increase in the rate of a reaction of order 2?
For a second-order reaction, the rate of reaction is proportional to the square of the concentration of the reactant. Therefore, to achieve a tenfold increase in the reaction rate, the concentration must be increased by a factor of √10 (approximately 3.16). This is because if the concentration is increased by this factor, the rate will increase by (√10)² = 10.
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.
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.'
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.
How does temperature increase cause the rate of reaction to increase?
The movement of molecules and collisions are increased at high temperature.
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 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.
