Which of the following will have very high rate of reaction ?
Correct answer: D. all of above
- A. Double decomposition reaction
- B. Neutralization reaction
- C. Ionic reactions
- D. all of above
Explanation
Ionic reactions in aqueous solution are usually very rapid because oppositely charged ions react directly without breaking strong covalent bonds. Neutralization and many double-decomposition reactions are ionic reactions, so they are commonly treated as fast in introductory chemistry. Students may hesitate over a because not every double-decomposition reaction is equally fast, but the intended general classification gives d.

About Factors Affecting Rate of Reaction
Reaction rate depends on the nature and concentration of reactants, pressure for gases, temperature, surface area and catalysts. Collision theory explains these effects through collision frequency, orientation and activation energy, while questions often distinguish a catalyst's effect on reaction rate from its lack of effect on equilibrium composition.
