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

Reaction: A = B + C

Reaction is run in an isothermal constant volume reaction vessel. Initially, before any reaction has occurred, the vessel is filled with pure A at 1 atm and 400K. The equilibrium conversion, epsilon and final pressure of the system is to be determined.

2. Relevant equations

I have no idea where to progress from where I am at. My attempt to the question is descried below.

3. The attempt at a solution

Component Initial Dissociation yi

A 1 1-epsilon (1-eps)/(1+eps)

B 0 epsilon eps/(1+eps)

C 0 epsilon eps/(1+eps)

Ka = Kp*Ky*Kf/Kf0

Kf0 based on fugacity at 1 atm

Kp = (P2/1)1

Ky = (eps^2/(1+eps)^2)

Kf = still unknown but based on (f/p)

Ka = 1.0

since ln(Ka1/Ka2) = integral(H/RT) dt = 0 for isothermal process

Ka1 = Ka2 where Ka = 1 for standard state of p=1 atm and T = 400K

Would anyone on here have any idea how to go about this question?
