Residual Entropy

Postby Hadji Yono-Cruz 2L » Sun Feb 17, 2019 11:08 pm

I know boltzman equation is S= k ln W, but when am I supposed to use S= R Ln W ( k times avogadro's number is R)?

I haven't come across problems incorporating what you mentioned. Since the value of W is yielded by (number of available positions)^(number of particles), then I think it's fair to assume that you will be using the value of k rather than R. W is in terms of individual particles and so is k, so I think you'll be safe just using k in problems that require the usage of this equation.

As I understand it, for the purposes of this course, S = k ln W should suffice. From the homework problems that I’ve seen, I haven’t used the second equation you mentioned.
