Question

The total kinetic energy of 1 mole of oxygen at … is :
[Use universal gas constant … mole K]

Accepted Answer

Option A. The total kinetic energy of a mole of an ideal gas can be determined by using the equipartition theorem, which states that the energy is equally distributed among degrees of freedom. For a diatomic molecule such as oxygen (…), there are 5 degrees of freedom (3 translational and 2 rotational - assuming the vibrational modes are not excited at room temperature), so each degree of freedom has an average energy of … per molecule, where … is the Boltzmann constant and … is the temperature in kelvins.
