An oxygen (0,) molecule is adsorbed on a patch of surface (see sketch at right). This patch is known to contain 784 adsorption sites. The (O,) 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 1089 adsorption sites are now available for the molecule. Calculate the change in entropy. One way an 0, molecule could be adsorbed on a patch of surface with 16 sites. Round your answer to 3 significant digits, and be sure it has the correct unit symbol.

For D. Determine the mechanism
The first step in the heterogeneoushydrogenation of ethylene is adsorption of theethylene molecule on a metal surface. One proposed explanation for the “sticking” of ethylene to a metalsurface is the interaction of the electrons in the C—C π bond with vacant orbitals on the metal surface. (a) If thisnotion is correct, would ethane be expected to adsorb to a metal surface, and, if so, how strongly would ethane bindcompared to ethylene? (b) Based on its Lewis structure,would you expect ammonia to adsorb to a metal surfaceusing a similar explanation as for ethylene?

Two helium atoms adsorb to a surface which has 20 sites to which it can adhere. What is the entropy of the system?
The compound α-tocopherol, a form of vitamin E, is a powerful antioxidant that may help to maintain the integrity of biological membranes. R.H. Bisby and A.W. Parker (J. Amer. Chem. Soc. 117, 5664 (1995)) studied the reaction of photochemically excited duroquinone with the antioxidant in ethanol. Once the duroquinone was photochemically excited, a bimolecular reaction took place at diffusion-limited rate. (a) Estimate the rate constant for a diffusion-limited reaction in ethanol. (b) The reported rate constant was 2.77 × 109 dm3 mol−1 s−1. Estimate the critical reaction distance if the sum of diffusion coefficients is 1 × 10−9 m2 s−1.
