The catalyst decrease the needed activation energy.
Catalysts decrease activation energy.
Temperature
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.

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.
A catalyst increases the reverse rate of the reaction
A catalyst lowers the activation energy of a reaction.
Yes, a catalyst is typically required in small amounts to increase the rate of a chemical reaction without being consumed in the process. It works by providing an alternative reaction pathway with lower activation energy, allowing the reaction to proceed faster.
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
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.
Increasing temperature, increasing concentration of reactants, and adding a catalyst are all factors that can increase the rate of a chemical reaction. This is because they either provide more energy for the reaction to occur (temperature), increase the frequency of reactant collisions (concentration), or lower the activation energy required for the reaction to proceed (catalyst).
A catalyst is something that is added to a reaction to lower the energy required to start it: the activation energy.
