Question description

  1. What energy is commonly employed in nutrition science?
  2. Describe what is meant by a exothermic reaction
  3. explain what is meant by the term “entrophy”
  4. predict whether each of the following processes increases or decreases entropy, and explain your reasoning. a) burning log in a fireplace b) boiling of water
  5. energy is required to break chemical bonds during the course of a reactin. why is energy released?
  6. provide an example of a reaction that is extremely fast, perhaps quicker than the eye can perceive.
  7. sketch a potential energy diagram for a reaction that shows the effect of a catalyst on an endothermic reaction
  8. what is the relationship between the forward and reverse rates for a reaction at equilibrium.
  9. can a catalyst alter the position of the equilibrium
  10. a change in pressure could have the greatest effect on which type of equilibria: gaseous, liquid, or solid
  11. write a valid equilibrium constant expression for the reaction N204(g)<======> 2no2(g)
  12. True or Falso: The position of the equilibrium for an endothermic reaction will shift to the right when the reaction mixture is healed. Explain your reasoning
  13. write the equilibrium constant expression for this reaction: C(s) + H2O(g)<===> CO(g) + h2(g)
