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...

2. (50 pts.) Consider the reaction A → R+S with rate -ra = k (oth order) in an isothermal batch reactor. The initial reaction mixture contains reactant A only. When the reaction is executed at constant volume conditions, its half-life is found to be t1/2 = 7.5 min. Suppose that the reaction is executed under isobaric conditions (assume that g = 1). Find the time required for the reaction to be completed.
