A catalyst works by essentially speeding up the rate of reaction or changing other environmental factors, such as increasing yield. Although this is technically not the mechanism by which catalysts usually work, it's a sufficient idea of how catalysts benefit reactions.
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.
s
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
A catalyst increases the reverse rate of the reaction
No, it is not true that a catalyst raises the activation energy of a reaction. In fact, a catalyst lowers the activation energy, allowing the reaction to occur more easily and at a faster rate. By providing an alternative pathway for the reaction, catalysts facilitate the formation of products without being consumed in the process.

A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction
To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.
A catalyst lowers the activation energy of a reaction.
Yes,catalysts help the reaction go faster.
A catalyst increases the reverse rate of the reaction
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
