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 No change Either A or B, depends on the type of reaction Decrease Increase No change Either A or B, depends on the type of reaction Decrease 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 Increased temperature reduces the activation energy Collision frequency increases Value of threshold energy decreases Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Collision frequency increases Value of threshold energy decreases ANSWER DOWNLOAD EXAMIANS APP
