Rate at which reaction proceeds is directly proportional to
Correct answer: B. concentration of reactants
- A. concentration of products
- B. concentration of reactants
- C. Volume of reactants
- D. Volume of products
Explanation
It depends on the concentration of reactants According to law of mass action, rate is directly proportional to the product of the active masses of the reaction or the molar concentrations of the reactantsIt depends on the concentration of reactants It depends on the concentration of reactants

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.
