Constant volume batch reactors are the widely used industrial batch reactors.

(a) True

(b) False

The question was asked during an interview.

My question comes from Batch Reactor Design Equations topic in portion Ideal Reactors for a Single Reaction, Conversion and Reactor Sizing of Chemical Reaction Engineering

Percy prepares vegetable curry (liquid) in a pressure cooker. If the raw potatoes are P, the raw tomatoes are T, the raw onions are O, and the cooked meal is M, then 2P + T + O → 3M may represent the cooking process. Sometime during the process, Manu opens the lid and checks the curry to find that the potatoes are half-cooked (take XP = 0.5). Volume of the cooker is 5L and CPo = CTo = COo = 1.5. What can you say about the composition in the cooker at the instant of time when the lid is opened, if initial temperature was 310K?

(a) XT = 0.35

(b) CO = 1.125

(c) T = 380K

(d) CM = 2.5
