The average translational kinetic energy of a molecule is given by:

(3/2)kT = (3/2) × (1.38 × 10^-23 J/K) × T

Since the temperature is the same for both O2 and N2 molecules, the average translational kinetic energy will be the same:

0.048 eV = (3/2)kT

The mass of the molecule does not affect the average translational kinetic energy.

Therefore, the translational kinetic energy of N2 molecules at the same temperature is also:

0.048 eV

Explanation

To find the work done, we need to integrate the force with respect to the displacement.

Given:

F(x) = 7 - 2x + 3x^2 N

x_initial = 0 m

x_final = 5 m

Work done (W) is the integral of force (F) with respect to displacement (x):

W = ∫[x_initial, x_final] F(x) dx

= ∫[0, 5] (7 - 2x + 3x^2) dx

Evaluating the integral:

W = [7x - x^2 + x^3] from 0 to 5

= (7(5) - 5^2 + 5^3) - (7(0) - 0^2 + 0^3)

= (35 - 25 + 125) - 0

= 135 J
