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 Question 7 2 pts The reaction A + 2B + 2C is conducted in a variable volume batch reactor, which of the following statements is CORRECT? It is expected that the volume of the reacting fluid will increase. It is not possible for the reaction to proceed. Volume of reacting fluid will increase with increase in conversion. It is expected that the volume of the reacting fluid will decrease
