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

(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
