The catalyst decrease the needed activation energy.
Catalysts decrease activation energy.
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.
catalyst decreases the activation energy of a chemical reaction, thereby increasing the effective collisions and hence the rate of the chemical reaction

A catalyst lowers the activation energy of a reaction.
A chemical catalyst is a substance that lowers the required activation energy of a reaction. The activation energy is the amount of energy required to "activate" or start a process, this can be in the form of many things, such as heat. A chemical catalyst can be seen as a kind of shortcut in a chemical process to speed things up. A catalyst can also be used to increase the activation energy, so that the reaction will slow down. This is useful for slowing down reactions that are normally too fast to witness.
The overall enthalpy change in a common reaction would not change. Only the path to get there would change. A catalyst basically lessens the activation energy required to get the reaction to take place.
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
A catalyst is something that is added to a reaction to lower the energy required to start it: the activation energy.
The presence of a catalyst in a reaction will lower the activation energy required to complete the reaction. The catalyst is not used up in the reaction, it is just there to speed it up.
Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.
They are called Enzymes
Adding a catalyst will make the reaction happen faster because the catalyst makes the Activation Energy (the energy required for the reaction to take place) to lower. Meaning more molecules can acquire this lower number of energy. A chemical reaction that involves a catalyst is a special type. A catalyst, in a given chemical reaction, is something that is both an input *and* an output of the reaction equation. What that means, practically, is that a small amount of catalyst is enough to process any amount of the other inputs. (More catalyst means that a given amount will be processed faster.)
