Choose the one which is not an assumption of collision theory of reaction rate:
Correct answer: D. For hydrogen molecule formation from atoms require specific orientation
- A. For chemical reaction to occur molecule / particles must collide
- B. For reacting molecules / particles must possess a certain minimum amount of energy, the activation of energy
- C. Every collision is not productive
- D. For hydrogen molecule formation from atoms require specific orientation
Explanation
Collision molecular theory says that for a reaction to occur, reactants must collide in a specific orientation with a specific energy. As hydrogen is a diatomic molecule so it does not require a specific orientation.

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.
