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