Catalysts doesn't affect the energy of reactions
Catalysts lower the activation energy of a chemical reaction.
Catalysts speed up reactions by reducing the activation energy.
an enzyme
A catalyst
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
A catalyst increases the reverse rate of the reaction
Catalysts speed up reactions by reducing the activation energy.
Catalysts greatly reduce the amount of activation energy needed to begin a reaction.
Enzymes are biologic catalyst that speed up chemical reactions by lowering its activation energy Ea

It is true that a catalyst is used in chemical reactions to help speed up the reaction by reducing activation energy.
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
A catalyst increases the reverse rate of the 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.
yes. lowers it.
The activation energy is reduced.
