Why does increasing the concentration of reactants increase the reaction rate?A.The temperature increases with higher concentrations.B.Collisions of the right energy are more likely.C.Some of the reactants are likely to act as catalysts.D.Increasing the concentration changes the rate constant.SUBMITarrow_backPREVIOUS

Why does increasing temperature generally increase the rate of a chemical reaction? A. It increases the amount of reactant. B. It decreases the size of the reactant particles. C. It causes the particles of the reactants to move faster and collide more often. D. It increases the space between reactant particles, so they have more room to move apart.

As the temperature of a chemical reaction increases, the rate of reaction increases becauseA fewer particle collisions occurB the required activation energy increasesC more effective particle collisions occurD the concentration of the reactants increases

Which of the following tends to increase the rate of a chemical reaction?A.Decreasing the concentration of the reactantsB.Increasing the temperature of the reaction mixtureC.Increasing the amount of solvent usedD.Using larger particles of solid reactants

Which of the following would cause a decrease in the rate of a chemical reaction? Which of the following would cause a decrease in the rate of a chemical reaction? An increase in the concentration of the reactants. An increase in temperature. An increase in the particle size. The addition of a catalyst

Why does increasing the temperature speed up a reaction?A.It makes the energy of the reactants the same as the products.B.It forces the reaction to favor the product side at equilibrium.C.It increases the concentration of molecules so more will react.D.It provides energy to overcome the activation energy.
