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.
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.
A catalyst is a substance which speeds up the rate of reaction. After the reaction it remain chemically unchanged. It does NOT affect the position of equilibrium. There can also be negative or "poisoned" catalysts as in Rosenmunds 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.
The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!

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

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.
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).
A catalyst reduces the amount of energy required to produce the reaction. This speeds up the reaction and causes it to finish more quickly. Raising the temperature will also speed up a reaction.
