was chosen we measured the co2 absorption rate in aqueous DEEA solution the enhancement faction (E=M) for the
co2-DEEA system at 303 k and (DEEA)0 = 2 kmol/m3 was determined and compared with those reported in table 2 the comparson is shown in table2 the comparison is show in table 3 and it is obvious that the values of Ein presence of PZ are higher furthermoure the value of Eincreases with an increase in PZ concentration (figure 2) the observed reaction rath constants for this system were measured A plot of Kobs VS (PZ)0 at 308k is shown in figure 3 the value of Kobe (=Kobe(DEEA)0) rises with PZ concentration A typical value at (PZ)0=0.1 kmol/m3 was found to be 2245 L/s from eq 24 and from the knowledge on k' at 303k (vis., 173 m3/(kmol s), see ref 4 ), the value of the rate constant for
