Question

How does the rate of a reaction depend on the size of the particles of reactants? give suitable example​

Answer 1

Answer:

By decreasing the particle size of a reactant, we are increasing its surface area. The greater the surface area, the higher the chance of collisions, thus the faster the rate of reaction. The smaller the particle size the faster the reaction.

Answer 2

• The rate of a reaction decreases with increase in particle size.
• Smaller the size of the reactant particles taking part in a reaction faster is the rate of reaction.
• Smaller the particle size of a reactant, greater the surface area of the reactant, thus higher the chance of collisions and hence faster the rate of reaction.
• Example - If a solid is divided into smaller pieces, surface area of reacting molecule increases, thus, more particles are able to react and hence the reaction rate increases.
