Answer #1

Here, as the average kinetic energy of a molecule

Average kinetic energy = 1.5 * k * T

Average kinetic energy = 1.5 * 1.38 *10^-23 * 248

Average kinetic energy = 5.134 *10^-21 J

the Average kinetic energy is 5.134 *10^-21 J

for the oxygen molecule

as the average kinetic energy of a molecule

Average kinetic energy = 2.5 * k * T

Average kinetic energy = 2.5 * 1.38 *10^-23 * 248

Average kinetic energy = 8.56 *10^-21 J

the Average kinetic energy is 8.56 *10^-21 J

The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed=√3RTM where R=8.314 J/(mol⋅K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram‑meter squared per second squared (kg·m2/s2). What is the rms speed of Cl2 molecules at 471...
