An oxygen (O,) molecule is adsorbed on a patch of surface (see sketch at right). This patch is known to contain 1156 adsorption sites. The (0, ) molecule has enough energy to move from site to site, so it could be on any one of them. Suppose part of the surface becomes inaccessible, so that only 729 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.
