  1. Question 1

    Q1. The rate of a chemical reaction depends on the nature of chemical reactants because:

    • A) The energy of activation differs from one reactant to another
    • B) Some of the reactants are solid at room temperature
    • C) Some of the reactants are colored
    • D) All are correct

    Answer: The energy of activation differs from one reactant to another

    Explanation: Different chemical reactants have different bond energies and electronic structures, resulting in different activation energies that directly determine how fast a reaction proceeds.
