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 A space time of 3 hours for a flow reactor means that Three reactor volumes of feed can be processed every hour The time required to process one reactor volume of feed (measured at specified conditions) is 3 hours It takes three hours to dump the entire volume of the reactor with feed Conversion is cent per cent after three hours Three reactor volumes of feed can be processed every hour The time required to process one reactor volume of feed (measured at specified conditions) is 3 hours It takes three hours to dump the entire volume of the reactor with feed Conversion is cent per cent after three hours 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 Value of threshold energy decreases Fraction of molecules having threshold energy increases Collision frequency increases Increased temperature reduces the activation energy Value of threshold energy decreases Fraction of molecules having threshold energy increases Collision frequency increases Increased temperature reduces the activation energy ANSWER DOWNLOAD EXAMIANS APP
