ChE 321 - Final Closed Book Section A gas-liquid reaction is being run in a sitrred-tank reactor. When the stirring rate is increased, the conversion in the reactor increases. - correct answer Mass transfer limitations exist which are lessened when stirring rate is increased It is noted that when a species, which doesn't show up in the reaction stoichiometry, is added to a reaction mixture the catalytic reaction rate goes down. When this species is removed, the catalytic reaction rate goes ...
