Recalling Equation (3-44), we have

u = u,(l +EX) - -
p To

Neglecting Neglecting pressure drop in the reaction, P = Po, yields
pressure
drop, P = Po
u = uo(l +ex)
TO

If the reaction is also carried out isothermally, T = To, we obtain

u = uo(l +EX)
Isothermal 1 --x

The concentration of A initially is equal to the mole fraction of A initially multiplied
by the total concentration. The total concentration can be calculated from an equa-
tion of state such as the ideal gas law:

1485 kPa
= 0.28 1
8.314 kPa- dm3/mol. K X 500 K

= 0.1 m0Vdm3
