1.	What will happen if at equilibrium the concentration of one of the reactants is increased?(a) equilibrium will shift in the forward direction(b) equilibrium population will not change(c) equilibrium will shift in the backward direction(d) equilibrium will move to and froI have been asked this question in an interview for internship.My doubt stems from Factors Affecting Equilibria topic in division Equilibrium of Chemistry – Class 11
Answer» The correct ANSWER is (a) equilibrium will shift in the FORWARD direction To explain: As per the Le chatelier’s principle, if the concentration of ONE of the reactants is increased at equilibrium the equilibrium will shift in the forward direction and vice versa is also possible. Therefore we can say that there is an EFFECT of change of concentration on equilibrium.
