greater than the energy stored in the bonds of the products
Why?
Because when a chemical bond is formed, the resulting compound has less potential energy than the substances from which it was formed. Energy is always released when a bond is formed. The greater the energy released during the formation of a bond, the greater its stability. Consider the following reaction:
B + C ==> BC + 100 joules
The bond formed has less energy than the reactants because it released energy to form the resulting compound.
Exothermic means energy is being released. More energy is stored in the reactants, because that energy was released to form the compound.

Does an exothermic reaction contain more chemical energy than reactants?
depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.
What happens to the reaction during endothermic and exothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
How do endothermic and exothermic differ?
Exothermic reactions release energy (usually as heat) into the surrounding environment - endothermic reactions absorb energy from the surrounding environment. Note that exothermic reactions are capable of turning into runaway reactions as the heat of reaction often speeds up the rate of reaction (releasing more heat, etc). Endothermic reactions are, usually, self moderating as a limited amount of energy is capable of being drawn from the surrounding environment.
Does enthalpy of reaction affect the rate of a reaction?
The enthalphy of a reaction does not influence the rate of reaction, it may however influence the rate of the reverse reaction, as we now would have a change in potential energy (for example an exothermic reaction requires more energy to go in the reverse then does an endothermic). This is why you can consider some products thermodynamically favourable - as they are the exothermic product which would require more energy to turn back towards reactants then to stay as products. Overall rate is not seen in the various rate law or rate of reaction equations utilised such as arrhenius temperature dependance or the rate law equation. Rate is indepedant of enthalpy WRT to forward reaction.
In a combustion reaction between butane and oxygen which contains more energy reactants catalyst products or products and reactants contain the same amount of energy?
Every combustion process is exothermic (the release of heat and light) so the products have low energy as compare to reactants which are in this case Butane and oxygen.
Does an exothermic reation release energy into its surroundings and its products have more energy to the reactant?
Two different answers:Yes, an exothermic reaction releases energy into its surroundings No, its products do NOT have more energy than the reactant(s)
Do endothermic reaction have reactants with more energy than its products?
Kinetic energy has more energy than products.

What is a chemical reaction in which more energy is taken in than given off?
Exothermic Reaction
How do you tell endothermic reaction from an exothermic reaction by looking at the chemical equation?
You have to add up the bond energies of all the bonds on the products side and the reactants side. When bonds are formed energy is released. Conversely energy has to be put into a system to break bonds (like smashing a block of ice with a baseball bat) If there is more bond energy on the products side bonds were created (energy was released) which means the reaction is exothermic. If there is more bond energy on the reactants side, bonds were broken (energy put in) and so the reaction is endothermic.
Which is more energy given off than taken in A exothermic reaction an endothermic reaction a diluted solution or a concentrated solution?
exothermic
How can endothermic and exothermic reactions work alike?
Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.
Is a light bulb an exothermic reaction?
More technically, the energy is released.
Which contains more chemical energy endothermic or exothermic?
An endothermic reaction contains more chemical energy.

Endothermic reactions are, usually, self moderating as a limited amount of energy is capable of being drawn from the surrounding environment.
What is endothermic and exothermic?
Exothermic refers to a reaction that produces heat. When you balance the equation the energy released when new bonds are formed is greater than the energy use when bonds are broken. An endothermic reaction takes in heat as it requires more energy to break its bonds than it has from the bonds it creates.
