Question

The isothermal and isobaric gas phase reaction A → B + C follows an elementary rate law and is to be carried out in a CSTR. The reaction constant k = 1.20 s^-1 when the reaction temperature T = 300 K.

(a) When pure A is fed to a CSTR at 300K and a volumetric flow rate of 5 dm3 /s,a conversion of X = 0.6 is achieved. Please determine the volume of the CSTR.

(b) If the CSTR’s volume is changed to 20 dm³ and pure A is still fed to the reactor at 300K and a volumetric flow rate of 5 dm³ /s, please determine the new conversion X.

(c) If the reaction temperature T increases to 320K, k = 2.50 s^-1 , please determine the activation energy of the reaction (when T = 300 K, k = 1.20 s^-1 . Take R = 8.314 J·mol^-1 ·K^-1 ).
