Question
What effect does the concentration of reactants have on the rate of a reaction?A.Increasing the concentration decreases the rate of the reaction.B.Changing the concentration has no effect on the reaction rate.C.The effect of concentration on rate varies within the reaction.D.Increasing the concentration increases the rate of the reaction.SUBMITarrow_backPREVIOUS
Solution
D. Increasing the concentration increases the rate of the reaction.
This is because when the concentration of reactants is increased, there are more particles present in the same volume. This increases the likelihood of collisions between reactant particles, leading to more successful collisions per unit time, and thus increasing the rate of the reaction.
