(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Vapor mercury is to be adiabatically and reversibly compressed from 0.1 MPa to 10 MPa in a

continuous process. Compute the work required in Joules per mole.

Properties of Mercury

Tc =1735 K, Pc =161 MPa.

ω=-0.1644, CP/R =2.5

2. Relevant equations

The Peng Robinson Equation of State....(see attached file)

work=delta(H)

H=Cp*delta(T)

(Cp/R)*R= Cp

R=8.314

3. The attempt at a solution

I'm having trouble getting started. I think I need to solve PREOS for the T to find the change in T. But that can't be all because I still don't know the density. So that's one equation and twp unknown. On top of that, I have Pc, Tc rather than T and P. If I don't have Tr I can't find those.

It must be rather apparent that I need some serious help. If anyone can help get me on the right track I would appreciate it very much.

Thanks in advance.
