Question

In a steady-state reactive system, 1 molar each of NaOH and HCl are supplied to the system both at the rate of 100 L/min, then what is the amount of NaCl produced?

(a) 1 molar

(b) 2 molar

(c) 3 molar

(d) 4 molar

The question was asked during an online exam.

Question is from Accounting for Chemical Reactions in Material Balances in chapter Introduction to Material Balances of Basic Chemical Engineering

Answer 1

The correct answer is (a) 1 molar

To explain I would say: The balanced reaction of the system is NaOH + HCl -> NaCl + H2O, => amount of NaCl = amount of HCl = amount of NaOH = 1 molar.
