A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.

Why does catalyst affect reaction speed?
The activation energy is reduced.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
How does a catalyst affect the rate of an industrial reaction?
Catalysts speed up reactions by reducing the activation energy.
What speeds up in chemical reaction?
There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.
Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
Catalyst do what to a reaction rate?
Catalysts affect reaction rates by providing an alternate route of reaction with lower activation energy. Therefore, they speed up the process they are catalyzing in both the forward and reverse directions.
What is the purpose of phosphoric acid in the synthesis of aspirin?
to serve as a catalyst and speed up the reaction
What will change when a catalyst is added to a chemical reaction?
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
What ways can a catalyst affect a chemical reation?
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.
What effect does a promoter catalyst have on the position of the equilibrium?
By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
Is catalyst a product of chemical reaction?
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
Which component is affected when a catalyst is added to a chemical reaction?
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
