  1. Question 1

    Q1. According to the collision theory, which factor primarily determines the rate of a chemical reaction at a constant temperature?

    • A) The total number of molecules in the container
    • B) The frequency of effective collisions
    • C) The average velocity of all molecules
    • D) The total volume of the reaction mixture

    Answer: The frequency of effective collisions

    Explanation: Reaction rate depends on the number of effective collisions per unit time. Option D is incorrect because not all collisions lead to reaction.
