### Van't Hoff Equation

In the Van't Hoff equation, is the 2 R's in the equation both Boltemann's constant?

I'm pretty sure R is the ideal gas constant

Boltzmann's constant is used for calculating entropy. The R in the Van't Hoff equation is referring to the gas constant.

Usually Boltzmann’s constant will be indicated with a lower case k whereas the gas constant will be indicated with a uppercase R.
