When a reaction proceeds, what will happen to the concentration of reactants and products with time?
Correct answer: C. Concentration of products increases and reactants decreases
- A. None of these
- B. Concentration of reactants increases and of products decreases
- C. Concentration of products increases and reactants decreases
- D. Concentration of both reactants and products increases
Explanation
Reactants react with each other to form products in a chemical reaction.As the reaction proceeds, more reactants will react together to form products. Resultantly, the concentration of products will increase and the concentration of reactants will decrease. This will continue until the state of equilibrium is achieved in case of a reversible reaction.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
