Correct answer: B. In some cases molecularity of a reaction is the same as order of reaction

  • A. Molecularity of a reaction is same as the order of reaction
  • B. In some cases molecularity of a reaction is the same as order of reaction
  • C. Molecularity of a reaction is more than order of reaction
  • D. All are correct

Explanation

Molecularity of a reaction is sometimes same as the order of reaction, because order of reaction is experimentally derived. It is not necessary that molecularity is always same sa that of order of 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.
