Question

There is always a limiting reactant.

(a) True

(b) False

I got this question during an online interview.

I need to ask this question from Effect of Maintenance on Yields topic in division Homogenous Reactions of Bioprocess Engineering

Answer 1

Correct answer is (b) False

To explain: If all the reagents are added in exactly the right mole ratio then all of each reagent is used up, so there is no excess or limiting reagent. In this case you can use either reagent moles to work out the amount of product formed. Then both reagents will be fully consumed so neither is limiting.
