How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
How does a catalyst increase the rate of a chemical reation?
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy for the reaction to occur. This allows more reactant molecules to reach the activation energy threshold, making the reaction proceed faster. The catalyst itself is not consumed in the reaction and can be reused.
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 increases the rate of a reaction by lowering the activation energy?
A catalyst can increase the rate of a reaction by lowering the activation energy needed for the reaction to occur. Catalysts provide an alternative reaction pathway with a lower activation energy, allowing the reaction to happen more quickly.
How does a catalyst speed up a reaction at low tempertures?
A catalysts speed up the rate of reaction by providing an alternate pathway which has a lower energy of activation than the normal pathway.

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.
How enzymes works?
Provide an alternate pathway with a lower activation energy for a reaction
How does a catalyst increases the rate of a reaction?
By providing an alternative pathway with a lower activation energy.

How is activatiokn energy represented on an energy diagram?
Activation energy is represented as the energy difference between the reactants and the transition state on an energy diagram. It is the energy barrier that must be overcome for a chemical reaction to occur. The activation energy is depicted as the peak of the curve on the reaction pathway.

How does a catalyst speed up a reaction at low tempertures?
A catalysts speed up the rate of reaction by providing an alternate pathway which has a lower energy of activation than the normal pathway.
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
Is it true that another way to control the rate of a reaction is to change the activation energy needed?
Yes, altering the activation energy required for a reaction can impact the reaction rate. Lowering the activation energy makes it easier for the reaction to occur, speeding up the rate, while increasing the activation energy slows down the rate. This is often achieved by using catalysts to provide an alternative reaction pathway with lower activation energy.
What type of catalyst lowers the energy of activation for a reaction?
A catalyst lowers the energy of activation for a reaction by providing an alternative reaction pathway with lower activation energy. This allows the reactants to more easily overcome the energy barrier and proceed to form products at a faster rate.
