The irreversible, endothermic, elementary, liquid-phase reaction: 2A ---> B, is carried out adiabatically in a 100 liter PRF. Species A and inert liquid are fed to the reactor with concentrations CAo = 1.5 mol/l and CIo = 1.5 mol/l, while FAo=20 mol/min. The entering temperature is 400 K. Calculate the conversion and temperature at the exit of the reactor, given the additional information below: k = 0.0003 l/(mol*min) at 300 K E= 12000 cal/(mol* K) CpA = 10 cal/(mol*K), CpB...

The production of methyl bromide is an irreversible liquid-phase reaction that follows an elementary rate law. The reaction CNBr (A) + CH3NH2 (B)àCH3Br (C) + NCNH2 (D) is carried out isothermally in a semi-batch reactor. A solution of methylamine (B) in extra dry ethanol at a concentration of 0.025 mol/L is to be fed at a rate of 0.05 L/s to an solution of bromine cyanide (A) in extra dry ethanol contained in a glass-lined reactor. The initial volume of...

A batch reactor operating at near room temperature, 25°C, is currently taking six hours to reach ninety percent conversion for an irreversible second-order liquid-phase reaction. Account the time to fill, empty, and clean the reactor, this allows one batch to be handled during an ei hour work shift. ing for ght- There is now pressure to cut the reaction time in half, to three hours, so two batches can be handled during a shift. When the reactor temperature is increased...
