Respuesta :
Mary claims that two dilute solutions will have a lower reaction rate than two concentrated solutions, Mary is right because of Option A.
Dilute and Concentrated Solutions
The rate of reaction depends on the amount of solutes. A concentrated solution has large amount of dissolved solute, whereas a dilute solution has small amount of dissolved solute.
Therefore, Mary is right because there will be fewer successful collisions between reactants in the dilute solutions. Hence option A is Correct.
