Which of the following best explains why most chemical reactions proceed more quickly when the concentrations of reactants are increased? (2 points) at higher concentrations, reactant molecules move more quickly. the increased concentration increases the number of collisions between molecules. at higher concentrations, product molecules are able to catalyze the reaction. the products of chemical reactions are more stable at higher concentrations.
