Chapter 10 Flashcards
what is a chemical reaction?
a process that either forms or breaks the chemical bonds that hold atoms together.
all chemical reactions either?
release energy or require an input of energy
reactions that release energy is called?
exergonic reaction: reactants contain more energy than the products
reactions that require an input of energy is called?
endergonic reaction: products contain more energy than the reactants.
every chemical reaction requires?
an initial investment of energy whether its endergonic or exergonic
for every reaction there is a specific?
activatione nergy ea: the amount of initial energy is required in order for the reactant moleucles to contort so the bonds can break
where does this energt cme from?
often supplied in the form of heat that the reacts absorb from the environment. the heat causes the reactants to move more quickly so they collide more often.
- collisions also make the bonds
