Adding a catalyst a chemical reaction can occur with a lower activation energy.
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.
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.
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.

The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
A chemical reaction is affected by temperature, pressure, presence of a catalyst , radiation and concentration. Hope I helped...
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.

A catalyst alters the rate of a chemical reaction.
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.

To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.
A catalyst undergoes no chemical change during a chemical reaction.
A catalyst can improve the reaction rate or allows the realization of a chemical reaction with an energy lower than the activation energy.
