Describe the effect of changing the concentration of reactant particles on reaction rate 1-3 sentences.

Increasing the concentration of reactant particles generally increases the reaction rate. This is because there are more particles available to collide and react. Conversely, decreasing the concentration of reactant particles tends to decrease the reaction rate as there are fewer collisions occurring.

Changing the concentration of reactant particles can have a significant effect on the reaction rate. By increasing the concentration, there will be more reactant particles colliding with each other, resulting in a higher reaction rate. Conversely, decreasing the concentration will lead to fewer collisions and a lower reaction rate.

The change in concentration of reactant particles directly affects the reaction rate. As the concentration of reactant particles increases, the likelihood of successful collisions between the particles also increases, leading to a higher reaction rate. Conversely, decreasing the concentration of reactant particles decreases the frequency of collisions and lowers the reaction rate.
