Chemical Reaction Engineering Recycling back of outlet stream to the reactor from an ideal CSTR carrying out a first order liquid phase reaction will result in __________ in conversion. Increase Decrease Either A or B, depends on the type of reaction No change Increase Decrease Either A or B, depends on the type of reaction No change ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering With the same reaction time, initial concentration and feed rate, the reaction 2A → B is carried out separately in CSTR and P.F. reactor of equal volumes. The conversion will be Higher in CSTR Same in both the reactors Higher in P.F. reactor Data insufficient; can't be predicted Higher in CSTR Same in both the reactors Higher in P.F. reactor Data insufficient; can't be predicted ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The gas phase reaction 2A ⇋ B is carried out in an isothermal plug flow reactor. The feed consists of 80 mole % A and 20 mole % inerts. If the conversion of A at the reactor exit is 50%, then CA/CA0 at the outlet of the reactor is 43959 43898 43864 43833 43959 43898 43864 43833 ANSWER DOWNLOAD EXAMIANS APP
