Answer :
Answer:
I think the particle size
Explanation:
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.
increasing the particle size will decrease the rate of reaction.
conclusion:
The smaller the particle size the faster the reaction.
The statement which is not correct is that: the rate of a reaction increases with increasing particle size.
Discussion;
The addition of catalyst, increase in temperature and reactant concentration all are factors which increase the rate of a chemical reaction.
Decreasing the particle size of reactants also increases the rate of reaction. This is because upon decreasing particle size, the surface area of the reactants is increased and the reaction is able to take place at a faster rate.
