(a) What is the average translational kinetic energy of a nitrogen molecule at STP?

(a)

Kinetic energy is a function of temperature alone:

K = (3/2) · kb · T

= (3/2) · 1.38065×10⁻²³J/K · 273.15K

= 5.65687×10⁻²¹ J

(b)

K = (3/2) · n · R · T

= (3/2) · 0.5mol · 8.314472J/molK · 323.15K

= 2.015kJ
