A chlorine (Cl) atom is adsorbed on a small patch of surface (see sketch at right). This patch is known to contain 16 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. - 20 kJ 3.7 x 10

12:27 12-2 Analyzing Data... NAME Energy (kJ) NAME 1000 Many chemical reactions involve a change in energy. When the energy of the reactants is greater than the energy of the products, the reaction gives off heat and is exothermic. When the energy of the products is greater than that of the reactants, the reaction must absorb energy from the surroundings to occur and is endothermic. If the intermediate stage (the activated complex) is of a higher energy, then the reaction can only take place if the reactants are given an initial energy input (the activation energy). The graph shows energy diagrams that indicate how the energy changes as three reactions occur.
