  1. Question 1

    Q1. For the reaction A -> products, the rate law is rate = k[A]². If the concentration of A is doubled, the rate

    • A) doubles
    • B) quadruples
    • C) remains same
    • D) halves

    Answer: quadruples

    Explanation: New rate = k(2[A])² = 4k[A]², which is four times the original rate, thus quadrupling.
