Unformatted text preview: CHEM 110 Recitation 10 2 --------------------------------------------------------------------------------------------------------------------- 1A. The C–Cl bond dissociation energy of CF 3 Cl is 339 kJ/mol. What is the maximum wavelength of photons that can rupture this bond? (Consider the following: what is the energy of one photon? What is the relationship between E and λ ?) -------------------------------------------------------------------------------------------------------------------------------------------- 1B. The concentration of carbon monoxide (CO) that can cause health problems is 50 ppm. If a room at 82°C and 725 torr has a total of 1.0 × 10 6 mol of gas and 2 × 10 2 mol of CO, what is the concentration (in ppm) of CO? Is this enough to cause health problems? What is the partial pressure of CO in the room? --------------------------------------------------------------------------------------------------------------------- 2. Liquid properties A. Given the following pair of substances, which is expected to have the greatest surface tension? (Why?) Which will have the greatest viscosity? tension?...
