Catalysts greatly reduce the amount of activation energy needed to begin a reaction.
Catalysts doesn't affect the energy of reactions
A catalyst lowers the activation energy of the reaction so the reaction happens faster.
And the definition of a catalyst is a substance which speeds up the rate of reaction without undergoing any perminant chemical change.
Hope this helps
Catalysts greatly reduce the amount of activation energy needed to begin a reaction.
Catalysts increase energy and speed up chemical reactions.
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.
yes. lowers it.
The activation energy is reduced.
a catalyst lowers the activation energy for both the forward and reverse reaction. however, it does not change the potential energy of the reactants or products. it also does not affect the heat of reaction (delta h)
It lowers it, so the reaction is faster.
It lowers it, so the reaction is faster.
It lowers it, so the reaction is faster.
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.

it speeds up the process :)
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
The presence of a catalyst affects the activation energy of a reaction by lowering the activation energy, helping the reaction go faster and making it so the reaction does not have to use as much energy to fulfill the products.
