MCQ Class 11 Chemistry Chapter 6 Equilibrium Advertisement MCQ’s For All Chapters – Chemistry Class 11th 1. Equilibrium is best defined asStage where the concentration of reactants is less than that of productsStage where concentration of reactants is equal to that of productsStage where the rate of forward reaction is equal to that of backward reactionStage where the concentration of reactants is more than that of productsYour comments:Question 1 of 102.
