SUMMARY
The average kinetic energy of a nitrogen molecule at 25°C is calculated using the formula KE = (5/2) kT, where k is the Boltzmann constant (1.38 x 10-23 J/K). The correct calculation yields an average kinetic energy of approximately 6.1686 x 10-21 J. This value is not listed among the provided answer choices, indicating that all options are incorrect. The discussion clarifies that nitrogen molecules, being diatomic, have rotational kinetic energy contributing to their overall kinetic energy.
