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.
A catalyst is a substance that decrease the activation energy needed to start a ch-
emical reaction. As a result, a catalyst also increase the rate of the chemical reacti-
on, or makes the products form faster.
A catalyst is a substance that increases the rate of a reaction. It provides an alternate route for the reaction with a lower activation energy (EA); sometimes it is said that a catalyst "lowers the activation energy". A catalyst is NOT consumed by the reaction.
A catalist lowers the activation energy of a reaction.
Catalyst causes activation energy to decrease
Sort of wrong question as the definition of a catalyst is a component that increases rate of reaction without being consumed.
Decreases it
yes
it speeds up the process :)
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
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.
Catalysts doesn't affect the energy of reactions
The activation energy is reduced.
it speeds up the process :)
It lowers it, so the reaction is faster.
It lowers it, so the reaction is faster.
It lowers it, so the reaction is faster.

yes. lowers it.
Catalysts greatly reduce the amount of activation energy needed to begin a reaction.
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
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.)
