A chlorine (CI) and bromine (Br) atom are adsorbed on a small patch of surface (see sketch at right). This patch is known to contain 36 possible adsorption sites. The Cl and bromine (Br) atoms have enough energy to move from site to site, so they could be on any two of them. Suppose the Br atom desorbs from the surface and drifts away. Calculate the change in entropy. One way a Cl and Br ato 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.
