One can derive the following relationship between the a and b coefficients in the van der Waals equation of state and the second virial coefficient,

B2V=b−a/RT.

Given this, what is the correct expression for the Boyle temperature in terms of a and b?

TBoyle =0

TBoyle =RT

TBoyle =Rb-a

TBoyle =a/Rb
