chapter#6 Flashcards
what is the first law of thermodynamic?
concerns with universal energy
what is the second law of thermodynamic?
addresses the efficacy of energy transformations
A lion tackles an antelope down, the lion then eats the carcass of the antelope .What thermodynamic law is this?
The first law
A fox eating berries is what thermodynamic law?
the first law
what is the definition of entropy?
disordered second law
what is the definition of enthalpy?
equal to the total number of a molecules chemical bonds
what is the definition of endergonic?
products contain more energy than the reactants free energy must be put into the reaction from an outside source to allow it to keep going
what is the definition of exergonic?
releasing energy
what kind of reaction does gasoline in your car have?
exergonic
what is free energy
energy available to work
how do catalysts work?
by stressing the chemical bonds making them easier to break, by doing so it lowers the activation energy required to initiate a reaction
true or false. catalysts can valuate the basic laws of thermodynamics.
false
true or false. catalysts can make an endergonic reaction and proceed spontaneously.
false
what makes ATP unstable?
the high energy bonds
ATP hydrolysis can drive what type of process?
endergonic process
