Title: μ* in Raoult vs μ* in Henry for Chemical Potential
Post by: Mercento on September 15, 2019, 04:34:35 AM

I am pulling my hair out.
So for Raoult's law:
μ_i=μ∗_i+RTlnx_i

For Henry's law:

μ_B(T,p)=μ^ref_x,B(T,p)+RTlnx_B

So my question is, is μ∗_i = μ^ref_x,B(T,p) ? Or does one of them mean for when substance is in high concentration (solution) and the other for when substance in low concentration (solute)?

Really appreciate your assistance.
