Question

The design equation for Batch reactor in differential form is _______

(a) NA0\(\frac{dXA}{dt}\) = -rA V

(b) \(\frac{dXA}{dt}\) = -rA

(c) \(\frac{dXA}{dt}\) = -rAV

(d) NA0\(\frac{dXA}{dt}\) = -rA

I have been asked this question by my school teacher while I was bunking the class.

I would like to ask this question from Batch Reactor Design Equations topic in section Ideal Reactors for a Single Reaction, Conversion and Reactor Sizing of Chemical Reaction Engineering

Answer 1

Right answer is (a) NA0\(\frac{dXA}{dt}\) = -rA V

Explanation: To obtain the time required to achieve a certain conversion. Mole balance is written in terms of conversion and then differentiated to get the above equation.
