catalysts essentially reduce the energy it takes to make a chemical reaction go (meaning they lower the activation energy, if you're familiar with that).

catalysts are not consumed in the chemical reaction, so they can do this over and over again. also note: the effectiveness of catalysts (can) depend on temperature and concentration/amount

Essentially, catalysts speed up chemical reactions by reducing the amount of energy required for the reaction to occur. Catalysts are not consumed in the process, and so can do this many times. Some other factors that can affect a catalysts' ability to speed a process are temperature, concentration (of either the catalyst or the chemicals being reacted) and pH level. :) Good Luck

Catalysts are basically what starts the reaction. You need a catalyst to even get a reaction. Like a match for example. If you were trying to light \a candle, you couldn't just light the candle without some source of fire to start it. That source of fire would be your catalyst. A match works great for that obviously.

They decrease the activation energy of that reaction.

Catalysts lower the activation energy required for a reaction or makes it easier to react. With more molecules possessing the requirement to react, the rate of reaction increases.

they reduce the amount of energy required by the reactants to activate the chemical reaction without involving in it themselves

Catalysts speed chemical reactions but are not change by them?

True. A catalysts job is to increase the rate of reaction, but it must do so without (a) being changed by the reaction or (b) become incorporated into the final product.
