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
We are unsure what you are asking. Please be more specific with your question to get an answer. Thanks.

A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).
Many things lead to an increase in the rate of chemical reactions. These factors include: - Addition of Catalysts - Light (only in some reactions) - Increase in temperature - Increase in Pressure - Increase in amount of reactants
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
Increasing the temperature of the reactants can increase the rate of the chemical reaction.

a catalyst can affect the rate of a reaction. speeding it up.
These are called catalysts.
They are called catalysts.

Enzymes are considered to be catalysts; they increase the rate of a chemical reaction.
A substance that will increase the rate of a chemical reaction without becoming part of the products or being consumed in the reaction.
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
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.
