Best Answer

Yes, catalysts can initiate or speed up a reaction by lowering the activation energy required for the reaction to occur. They do not undergo any permanent changes during the reaction process and can be used repeatedly.

What effect does a catalyst have?

A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.


How does the present of a catalyst affect the rate of reactions?

A catalyst can increase the rate of a reaction by providing an alternative pathway with lower activation energy. This allows the reaction to proceed more readily, resulting in a faster reaction rate. The catalyst itself is not consumed in the reaction and can be used repeatedly.


Is a catalyst used up in a reaction?

Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.


What is the opposite reaction of a Catalyst?

The opposite reaction of a catalyst would be an inhibitor. An inhibitor slows down or prevents a chemical reaction from occurring, whereas a catalyst speeds up the reaction.


will a catalyst change the enthalpy of a reaction in a chemical reaction?

No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!

What is a precatalyst?

A precatalyst is a chemical compound that can be converted into an active catalyst through a chemical reaction or activation step. It is typically used in catalytic processes to initiate the catalytic cycle and enhance the efficiency of the catalyst.


Why a catalyst is not involved chemically in chemical reaction?

The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.


What effect does catalyst on a reaction?

A catalyst speeds up the rate of a reaction.

A catalyst is added to the fiberglass resin to do what?

A catalyst is added to fiberglass resin to initiate the chemical reaction that causes the resin to harden or cure. This process is known as polymerization, and the catalyst helps speed up the curing time of the resin, allowing it to form a strong and durable composite material.


How does a catalyst speed a reaction at low temperature?

A catalyst lowers the activation energy required for a reaction to occur, allowing the reaction to proceed more readily at lower temperatures. This is achieved by providing an alternative reaction pathway that is more favorable and requires less energy to initiate. As a result, the reactant molecules are more likely to collide in an orientation that leads to product formation.


What substance increases the rate of a reaction but is not itself changed by the reaction?

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. It works by providing an alternative pathway with lower activation energy for the reaction to occur, thus speeding up the reaction without being permanently altered itself.
