What else can I help you with?
Would a catalyst cause an endothermic reaction to become exothermic?
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
Can an enzyme make an endothermic reaction exothermic?
False. Not necessarily. Do not confuse kinetics with thermodynamics. Although an enzyme as a catalyst decreases the activation energy of the reaction, this says nothing about whether the reaction is ultimately endothermic or exothermic.
Which type of reaction requires more activation energy?
Endothermic reactions typically require more activation energy compared to exothermic reactions. This is because in an endothermic reaction, energy is absorbed from the surroundings to break bonds and form new ones, which requires more energy input to overcome the activation barrier.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
How is energy involved in a chemical reaction?
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.
Does endothermic have a high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants.

Which of the following conclusions can be drawn from the curves in the energy diagram?
. The reaction represented by curve B will go faster than the curve A reaction.
Would a catalyst cause an endothermic reaction to become exothermic?
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
Why does an exothermic reaction need activeation energy?
Exothermic reactions need activation energy to start, but they also need it to keep going to build up heat. At the end of the reaction, the products have less energy than the reactants. This produces heat. In order for this to happen, the exothermic reaction needs activation energy.
Can an enzyme make an endothermic reaction exothermic?
False. Not necessarily. Do not confuse kinetics with thermodynamics. Although an enzyme as a catalyst decreases the activation energy of the reaction, this says nothing about whether the reaction is ultimately endothermic or exothermic.
What graph shows the pathway of a reaction that absorbs energy?
A reaction that absorbs energy is endothermic and typically represented on a graph with a reactant energy level below the product energy level. This results in an increase in energy during the course of the reaction, with the energy barrier (activation energy) higher than that of an exothermic reaction.
What is striking a match an example of?
Striking a match is an example of an endothermic reaction. It is also an example of simple combustion and a chemical reaction.
What kind of reaction is once started will continue by itself?
No. It requires an energy input (the activation energy) before it can proceed. For some reactions the energy needed can be as low as simply heat from the room and others need thousands of Watts of electrical power.
Does a catalyst make a reaction exothermic?
I honestly think it would because a catalyst lowers the activation energy, the amount of energy needed to complete the reaction. Since the activation energy is lower, it is absorbing less energy. I guess if its becoming less endothermic, its becoming more exothermic. Hope this helped!
Which type of reaction requires more activation energy?
Endothermic reactions typically require more activation energy compared to exothermic reactions. This is because in an endothermic reaction, energy is absorbed from the surroundings to break bonds and form new ones, which requires more energy input to overcome the activation barrier.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
