Answer :
Correct answer is
D. It increases the number of collisions at the the right orientation.
D. It increases the number of collisions at the the right orientation.
The reaction rate is the speed at which the reaction proceeds to form the product. The concentration affects the reaction rate as it increases the number of collisions. Thus, option D is correct.
What are the factors affecting the reaction rate?
The rate of the reaction is affected by various factors that include concentration, temperature, catalyst, and the surface area of the substance. The higher the concentration of the reactant, the more will be the reaction rate.
The increased concentration results in an increase in the kinetic energy that is because of the collision of the molecules of the reactants. The collision is in the right orientation and direction and the thus, increases the rate of the reaction to form a product.
Therefore, the increased concentration increases the collisions.
