Question

If the kg amount of both the reactants is doubled. What is the extent of the reaction?

(a) 2

(b) 4

(c) 6

(d) 8

The question was posed to me during an interview.

Origin of the question is Terminology for a Reaction System-II in section Material Balances without Reaction and Material Balances Involving Reactions of Chemical Process Calculation

Answer 1

The correct choice is (a) 2

To explain I would say: If we double the kg amount of reactant, we double the moles. The extent becomes double.
