Question

What is the percentage conversion of the reactant?

(a) 83.33

(b) 73.33

(c) 63.33

(d) 53.33

This question was addressed to me in an interview for internship.

This is a very interesting question from Terminology for a Reaction System-IV topic in chapter Material Balances without Reaction and Material Balances Involving Reactions of Chemical Process Calculation

Answer 1

The correct option is (a) 83.33

To elaborate: percentage conversion = (moles of the limiting reactant in the feed that reacts) / (moles of the limiting reactant introduced in the feed).
