Rate at which a reaction proceeds is directly related to the
Correct answer: B. concentration of reactant
- A. concentration of product
- B. concentration of reactant
- C. volume of reactant
- D. volume of product
Explanation
According to law of mass action, the rate is directly proportional to the product of active masses of the reactants. Where active mass represents the molar concentration of reactants involved in the 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.
