Atmospheric concentrations of methane and ozone can vary depending on the location and altitude. Calculate the rate of the reaction at 288 K for a methane concentration of 1.7 ppm (by volume) and an ozone concentration of 5.2 ppm (by volume). Note that 1 ppm of CH4 by volume means 1 L CH4/106 L air. Assume standard temperature and pressure (STP) so that 1 mol of gas occupies 22.4 L.

Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.
