The amount of activation energy related to whether a reaction is exothermic or endothermic?
The amount of activation energy required for a reaction is independent of whether the reaction is exothermic or endothermic. Activation energy is the energy needed to reach the transition state, allowing reactants to be converted into products. Exothermic reactions release energy as products form, while endothermic reactions absorb energy. Therefore, both types of reactions can have varying amounts of activation energy, depending on other factors such as the specific reactants and the reaction pathway.
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.
How does an energy diagram shows exothermic reaction?
An energy diagram for an exothermic reaction illustrates the energy changes during the reaction process. It typically features the reactants at a higher energy level than the products, indicating that energy is released as the reaction proceeds. The diagram also shows an energy barrier, or activation energy, that must be overcome for the reaction to occur. The overall decrease in energy from reactants to products reflects the exothermic nature of the reaction, signifying that heat is released into the surroundings.
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.
Do Exothermic reactions not require any activation energy.?
Exothermic reactions do require activation energy to initiate the reaction, even though they release heat once they proceed. Activation energy is the minimum energy needed for reactants to overcome the energy barrier and transform into products. Once this barrier is crossed, the reaction can continue and release energy in the form of heat. Thus, while exothermic reactions release energy overall, they still need some energy input to get started.
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.

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.

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 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.
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.
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!
