What I did not expect was different § for the same Keq at constant p. See Extent for 1 atm and 300 atm. For example; @ 325 C & 1 atm, § = 3.75E-04 for the Gibbs, but § = 1.53E-04 for the CSTR-eq. Another example is @ 325 C & 300 atm, § = 5.36E-04 for the Gibbs, but § = 2.19E+00 for the CSTR-eq.
Since Keq = f(T) only, pressure should have no effect on it, but the CSTR-eq should correct § for pressure.
Any suggestions as to the deviations would likely add to my learning.
