Wild plants readily grow all by themselves yet the molecules of the growing plant have less entropy than the materials used to make the plant. How is it possible for a there to be this decrease in entropy for a process that occurs all by itsel
 
  A) A decrease in entropy does not necessarily mean that a reaction if favored to proceed on its own. It happens in this instance but not in others.
  B) There is no decrease in entropy when wild plants grow. All growing plants tend to display an increase in entropy.
  C) Wild plants don't grow all by themselves. When we consider the entire system, including the sun, we find an overall increase in entropy.
  D) Life on Earth arises on its own. It does not depend on entropy processes.

Question 2

Why don't the electrodes of a fuel cell deteriorate the way the electrodes of a battery do?
 
  A) As long as fuel is supplied, fuel cells don't run down, but car batteries die when the electron-producing chemicals are consumed.
  B) Fuel cell electrodes are made of graphite, which does not deteriorate.
  C) Fuel cell electrodes are self-replenishing thanks to the KOH-containing paste.
  D) Fuel cell do not use electrodes, so there are none to deteriorate.
