a review problem->where in the book?

Postby Payton Kammerer 2B » Sat Mar 14, 2020 8:43 pm

Where is the equation/background for the solution to this problem discussed in the textbook? I'm a little confused by it and I think reading a few paragraphs about this topic would help clear things up

"In the above question, the partial pressure of the product is doubled, obviously the above reaction is no longer at equilibrium, calculate the reaction Gibbs free energy, ∆Gr, under these non-equilibrium conditions.
PPCl =0.8bar PPCl =PCl =0.2bar Q= PPCl5 = 0.8 =20
∆G = ∆G° + RT ln Q rr
∆Gr=−RTlnK +RTlnQ ∆Gr=RTlnQ −lnK
∆Gr=RTln20 −ln10
∆Gr = 8.314 J.K−1.mol−1 × 1943 K ln 20 − ln 10
= +11.2 kJ.mol−1"

See class notes. I discussed this in class towards the end of thermo.
