The _____ of a chemical reaction refers to the rate of the reaction. - ANSWERkinetics List the four factors that control kinetics of a chemical reaction. - ANSWERThe nature of the reaction itself, the concentration of the reactants, the temperature, and the presence of a catalysts What color is the permanganate? - ANSWERpurple What color is the oxalate solution? - ANSWERcolorless What color change do you see in the rate of reaction lab when monitoring the chemical reaction between the oxalate and permanganate? - ANSWERThe color will change from a purple and fade to pink, which will fade to a peach-orange, which will fade to a pale yellow, which will fade to colorless What happens to the reaction rate when you reduce the amount of the reactants? - ANSWERThe reaction will be slower than the normal reaction because there will be less collisions occurring, causing the amount of successful collisions to be less and the reaction rate to be less What happens to the reaction rate when you increase the temperature of a reaction? - ANSWERThe number of collisions happening in the reaction increases and the amount of kinetic energy increases, causing the rate of the reaction to be faster What happens to the reaction rate when you use a catalyst? - ANSWERThe catalyst
