Week 2: Inorganic & Organic Chemistry Flashcards
What concept drives diffusion of substance dissolved in liquids, is the tendency of atoms & molecules to equilibrate with enviro & is a thermodynamic imperative to randomness & diffusion
Concept of entropy
T/F Concept of Entropy is the force that creates concentration of molecules
False
T/F In concentration gradients, molecules dispersed in solution will re-concentrate themselves randomly
False, once dispersed, molecules do not re-concentrate themselves
Concentration gradients is driven by the force of _________________
