How can an endothermic reaction be spontaneous at room temperature?
Exothermic, as endothermic reactions require 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.
Is the reaction of borax and water endothermic or exothermic?
Exothermic reaction
Is a combustion reaction an endothermic reaction?
No, it 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.
Why does exothermic reactions need activation energy?
so the reaction can get started
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.
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.

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!

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.
A reaction that gives out energy?
... is an exothermic reaction (opposite of 'endothermic')
A reaction that releases energy in the form of heat?
It is called an exothermic reaction. Example: a burning candle
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
A chemical reaction that requires a net input of energy?
"Activation Energy reactions"; Endothermic reactions require energy.
