Concept explainers
Ozone in the stratosphere absorbs ultraviolet light of wavelengths shorter than 320 nm, thus filtering out the most energetic radiation from sunlight. During this absorption, an ozone molecule absorbs a photon, which breaks an oxygen-oxygen bond, yielding an oxygen molecule and an oxygen atom:
(Here, hv denotes a photon.) Suppose a flask of ozone is irradiated with a pulse of UV light of wavelength 275 nm. Assuming that each photon of this pulse that is absorbed breaks up one ozone molecule, calculate the energy absorbed per mole of O2 produced, giving the answer in kJ/mol.

- The velocity distribution function of gas moleculesa) is used to measure their velocity, since the small size of gas molecules means that it cannot be measured in any other wayb) is only used to describe the velocity of particles if their density is very high.c) describes the probability that a gas particle has a velocity in a given interval of velocitiesarrow_forwardExplain why in the representation of a one-dimensional velocity distribution function for a particular gas, the maximum occurs for vi = 0 m/s.arrow_forwardExplain why the representation of a one-dimensional velocity distribution function for a particular gas becomes flatter as the temperature increases.arrow_forward
