Question

At dynamic equilibrium the concentration of both the reactants and products are ____________

(a) equal

(b) not equal

(c) cannot predict

(d) sometimes equal sometimes not equal

This question was posed to me during an interview.

My question comes from Equilibrium in Chemical Processes topic in portion Equilibrium of Chemistry – Class 11

Answer 1

Right option is (b) not equal

To explain I would say: A dynamic equilibrium in a chemical reaction, both forward and backward rates are always equal. As the reaction occurs the concentration of product increases and the concentration of reactants decrease at equilibrium they are not equal.
