Why does a lower concentration of dissolved particles decrease the reaction rate? a. it does not. a high concentration decreases reaction rate. b. when there are less dissolved particles, less collisions take place. c. concentration is measured inversely. a low concentration indicates a higher portion of dissolved reactant particles. d. the dissolved reactant cannot collide with enough energy to react because it is moving slowly when it is dissolved in a solution.

Option (B) is the correct answer.

Explanation:

Whenever there is less concentration of solute particles in a solvent then it means less number of solute particles are available. As a result, there will occur less number of collisions between the solvent and solute particles.

It means that there will be a decrease in rate of reaction.

But if there is more concentration of solute particles then it shows more number of solute particles are available for reaction. As a result, more number of collisions will take place between the particles of solute and solvent.

Hence, then there will occur an increase in rate of reaction.

Thus, we can conclude that a lower concentration of dissolved particles decrease the reaction rate because when there are less dissolved particles, less collisions take place.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
