O ENTROPY AND FREE ENERGY Calculating entropy change using the Boltzmann hypothesis An oxygen (0, molecule is adsorbed on a patch of surface (see sketch at right). This patch is known to contain 289 adsorption 8 0 sites. The (0, 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 576 adsorption sites are now available for the molecule. Calculate the change in entropy.

(a) Most commercial heterogeneous catalysts are extremelyfinely divided solid materials. Why is particle sizeimportant? (b) What role does adsorption play in the actionof a heterogeneous catalyst?
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?
For D. Determine the mechanism
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.
