B. Calculate the velocity of the N2 molecule.
C. Analyze the relationship between kinetic energy and molecular speed.
D. Discuss the implications of molecular motion in N2.

Answer 1

To calculate the kinetic energy of an N2 molecule, you need to calculate its velocity and then substitute it into the kinetic energy formula.

Step-by-step explanation:

The kinetic energy of a gas molecule can be calculated using the equation KE = 1/2 mv^2, where KE is the kinetic energy, m is the mass of the molecule, and v is the velocity of the molecule. In order to calculate the kinetic energy of an N2 molecule, we first need to calculate its velocity. To find the velocity, we can use the root mean square speed formula v = sqrt(3RT/M), where v is the velocity, R is the gas constant, T is the temperature in Kelvin, and M is the molar mass of the gas molecule.

Once we have the velocity of the N2 molecule, we can substitute it into the kinetic energy formula to find the value in Joules.

Therefore, the steps to calculate the kinetic energy of an N2 molecule are:

1. Calculate the velocity of the N2 molecule using the root mean square speed formula.
2. Substitute the velocity into the kinetic energy formula to find the value in Joules.
