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 Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Collision frequency increases Value of threshold energy decreases Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Collision frequency increases 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 Conversion is cent per cent after three hours 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 Three reactor volumes of feed can be processed every hour Conversion is cent per cent after three hours 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 ANSWER DOWNLOAD EXAMIANS APP
