Briefly reason.A chlorine (CI) atom is adsorbed on a small patch of surface (see sketch at right). This patch is known to contain 64 possible adsorption sites. The Cl atom has enough energy to move from site to site, so it could be on any one of them. Suppose a Br atom also becomes adsorbed onto the surface. Calculate the change in entropy. One way a Cl atom might be adsorbed on a surface with 16 sites. Round your answer to 2 significant digits, and be sure it has the correct unit symbol.
