An oxygen (0₂) molecule is adsorbed on a patch of surface (see sketch at right). This patch is known to contain 25 adsorption sites. The (0₂) molecule has enough energy to move from site to site, so it could be on any one of them. Suppose additional surface becomes exposed, so that 225 adsorption sites are now available for the molecule. Calculate the change in entropy. Round your answer to 3 significant digits, and be sure it has the correct unit symbol. One way an O, molecule could be adsorbed on a patch of surface with 16 sites.
