Molar Kinetic Energy?

Postby Sina Rahmani 4A » Fri Jan 22, 2016 6:25 pm

Chapter 8, question 103 asks to calculate the molar kinetic energy.
The Students' Solution Manual says to use the equation 3/2*RT.
Can someone derive this equation please? I understand that the units of R (J*/(K*mol)) and T (K) end up becoming J/mol when multiplied together. But where did this equation come from?
Thank you :D

I don't exactly know the derivation, but found this online; hope it helps! It shows a form of derivation and explains some of it.
