The average translational kinetic energy of nitrogen molecule

In summary, the average translational kinetic energy of a nitrogen molecule can be calculated using the formula 3/2 * k * T, where k is the Boltzmann constant and T is the temperature in Kelvin. This energy is directly proportional to temperature, and its unit of measurement is joules (J). The mass of a nitrogen molecule does not affect its average kinetic energy, and this energy is significant in determining the rate of chemical reactions as it influences the speed and frequency of molecular collisions.

1. The average translational kinetic energy of a nitrogen molecule at temperature is _____


check picture



2.



3. The Attempt at a Solution :
since nitrogen is diatomic then it has 5 degrees of freedom and therefore the average kinetic energy wouldn't be 3/2kt it would rather be 5/2kt and therefore E=1*10^-20

Yes but translational energy would still be 3/2kT.
 

Related to The average translational kinetic energy of nitrogen molecule

1. What is the formula for calculating the average translational kinetic energy of a nitrogen molecule?
