41.C
Explaination
°=° => Key points. A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism
42.B
°=° => Both postulates of the collision theory of reaction rates are accommodated in the Arrhenius equation. The frequency factor A is related to the rate at which collisions having the correct orientation occur.

45. A
Explaination
°=° => Raw food and cooked food should be stored separately in the fridge. Bacteria from raw food can contaminate cold cooked food, and the bacteria can multiply to dangerous levels if the food is not cooked thoroughly again. Always store raw food in sealed or covered containers at the bottom of the fridge.
46.B
°=° => Reaction rate increases when temperature increases, when concentration increases, and when solid reactants have more surface area available (e.g., when the reactants are in smaller pieces). Catalysts are chemicals that raise reaction rates without being consumed in the reaction.
