  3. What is the most important potential energy storage molecule in all cells?

    If Image Upload 4 of system is negative, has the disorder of that system increased or decreased?

    Given that cellular rxns take place in the liquid phase, how is H related to E in a cell?
    ATP.

    Decreased.

    They are essentially equal, since volume will essentially be constant for a liquid (or a solid) Image Upload 6
  4. If the products in a reaction have more entropy than the reactants and the enthalpy (H) of the reactants & products are the same, can the rxn occur spontaneosly?
    Yes, if Image Upload 8 and Image Upload 10

    Image Upload 12
  5. When there are equal concentrations of reactants and products, is the rxn spontaneous or nonspontaneous?
    Neither, since Keq = 1, Image Upload 14

  6. Theoretically, will all reactant and product system sreach equilibrium?
    Given enough time, yes.
  7. If you find the standard value of G, can you use it to study a reaction in a moose?
    No, must have concetnrations of A, B, C, and D. If G is positive (nonspontaneous), but [reactants] >> [products], the reaction will be favorable.
  8. Which equation is used when finding the Gibbs Free Energy of an actual rxn?
    Image Upload 18

  9. What is the difference between thermodynamics and reaction rates?
    Thermodynamics tell you whether the rxn can proceed w/o additional energy input, but tells you nothing about the speed!
