Decreasing a reactant’s particle size will increase the reaction rate.
- If decreasing the size of the particles then increase the number of particles in a constant volume . Because due to smaller particle size the surface area increases.
- So that for the reaction, reactant's have large surface area. And rate of reaction will be increased .
- But when concentration of reactant's will decreases then for the reaction have lower number of reactants. And rate of reaction will decrease.
- When temperature of reaction decreases then the speed of atoms will slow and rate of reaction also decreases.
- When particle size increases means decrease in surface area and also decreases the rate of reaction.
So that when reactant's particle size decreases then rate of reaction increases .
