Chemical Reactions And Energy Flashcards
What are the two different types of reaction?
Exothermic and endothermic
What are exothermic reactions?
Reactions that give out energy
What are endothermic reactions?
Reactions that take in energy overall

How would you summarize an exothermic reaction?
Reaction where the energy of the products is less than the energy of the reactants because energy in the form of heat has been given out to the surroundings
How would you summarize an endothermic reaction?
In an endothermic reaction the energy of the product is greater than that of the reactants because energy has been taken in from the surroundings
What is the term for the energy needed to start a reaction?
Activation energy
What is the term for a collision that starts a reaction?
A successful collision
What is combustion?
A type of reaction that involves a fuel burning in oxygen
What is combustion a process of?
Breaking bonds in reactants and forming bonds to make products
What kind of reaction is the breaking of a bond?
Endothermic
What kind of reaction is the formation of a bond?
Exothermic
What is necessary for a bond to be broken?
An amount equivalent to the bond energy needs to be put in
