Chemical Reaction Engineering An irreversible first order reaction is being carried out in a CSTR and PFR of same volume. The liquid flow rates are same. The relative conversion will Be more in PFR than in CSTR Depend on the temperature Be more in CSTR than in PFR Be same in both cases Be more in PFR than in CSTR Depend on the temperature Be more in CSTR than in PFR Be same in both cases ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Fraction of molecules having threshold energy increases Value of threshold energy decreases Increased temperature reduces the activation energy Collision frequency increases Fraction of molecules having threshold energy increases Value of threshold energy decreases Increased temperature reduces the activation energy Collision frequency increases ANSWER DOWNLOAD EXAMIANS APP
