57. Why does the rate of a gas-phase reaction increase when the temperature of the system is increased? A) Increasing the temperature makes the molecules move faster, which results in more molecular collisions. B) Increasing the temperature gives the molecules more energy, so more reactant molecules have enough energy to react together. C) Increasing the temperature makes the volume increase, which provides more space for the product molecules to occupy. D) Statements A and B are correct.
