Question 12 2 pts A zero order reaction is conducted in a backmix reactor. If this is replaced by a plugflow reactor of the same size, the conversion is doubled. By how many percent is the feed rate changed? 40% 20% 50% 30% Question 14 2 pts A 50% conversion of gaseous feed of pure A (1 mol/li) is obtained in a 2- liter mixed flow reactor. The rate can be represented by -ra = 0.05(CA)2 mol/li min. If the feed rate is doubled, what is the final concentration of A? O 0.9761 mol/li 0.916 mol/li 0.9838 mol/li O 0.618 mol/li
