The following table gives data on the adsorption of benzene by graphitized carbon black (P-33) at two surface coverages and two temperatures: \[ \begin{array}{ccc} v\left(\mathrm{cm}^{3} \mathrm{g}^{-1} \text {at } 25^{\circ} \mathrm{C}, 1 \mathrm{bar}\right) & 0.2 & 0.4 \\ t / \mathrm{C}^{\circ} & \multicolumn{2}{c} {\text {Pressure}(\mathrm{Pa})} \\ \hline 0 & 13 & 27 \\ 35.0 & 80 & 170 \end{array} \] Calculate the enthalpy of adsorption $\Delta_{\text {ads }} H$ at each coverage. (S. Ross and J. P. Oliver, On Physical Adsorption, p. 238. New York: Wiley-Interscience, 1964.)
For the adsorption of CF3CHFCl on Pd, the following data were obtained at 313 K θ | P (Pa) 0.757 | 1.00 x 10^-1 0.237 | 1.00 x 10^-2 0.030 | 1.00 x 10^-3 (a) Are these data more consistent with associative or dissociative adsorption? (b) If Vm = 89 cm^3 g^-1, calculate the value of Vads at 0.272 Pa. Show all your working.
