Question

___________ reactant in a chemical reaction is that would theoretically run out first if the reaction were to proceed to completion according to the chemical equation , even if the reaction did not take place.

(a) Excess

(b) Limiting

(c) Both excess and limiting

(d) None of the mentioned

I have been asked this question during an interview.

My enquiry is from Limiting and Excess Reactant-II in chapter Material Balances without Reaction and Material Balances Involving Reactions of Chemical Process Calculation

Answer 1

Right answer is (b) Limiting

The best I can explain: Limiting reactant in a chemical reaction is that would theoretically run out first if the reaction were to proceed to completion according to the chemical equation , even if the reaction did not take place.
