Which of the following scenarios will increase the likelihood of reactant molecules colliding with one another during a liquid chemical reaction?

Question

Quizplus · Accepted Answer

The rate of a reaction depends on the frequency at which reactant molecules collide with one another. By increasing the concentration of reactants, there are more molecules of reactants in a given space, which increases the likelihood that these molecules will collide with one another.
The question specifies that the reaction is liquid, which means that increasing the pressure will have no effect on the reaction rate, since this only affects gaseous reactions.
