Catalysts doesn't affect the energy of reactions

∙ 11y agoA 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

What is activation energy How does a catalyst affect activation energy?
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.
Does a catalyst affect a reaction activation energy?
yes. lowers it.
Why does catalyst affect reaction speed?
The activation energy is reduced.
Assuming that the reaction is at equilibrium what effect does the addition of a catalyst have on the equilibruim?
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)
How does the addition of a catalyst affect the energy activation of a chemical reaction?
It lowers it, so the reaction is faster.
How does the addition of catalyst affect the energy of activation of chemical reaction?
It lowers it, so the reaction is faster.
How does the addition of a catalyst affect the energy of activation of a chemical reaction?
It lowers it, so the reaction is faster.
How does a catalyst affect the speed of a reaction?
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.
How do catalyst affect the energy reactions?
Catalysts doesn't affect the energy of reactions
How does a catalyst affect the activation energy chemical reaction?
it speeds up the process :)
How does the presence of a catalyst affect the enthalpy change of a reaction?
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.
How does catalyst affect the activation energy of chemical 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.
