  1. Question 1

    Q1. If an SN1 reaction is occurring and the substrate concentration is doubled while the nucleophile concentration is tripled, the rate increases by factor of:

    • A) 2 times
    • B) 3 times
    • C) 6 times
    • D) No change

    Answer: 2 times

    Explanation: SN1 rate only depends on [RX]; doubling [RX] doubles the rate. Nu concentration has no effect. Option C incorrectly includes the nucleophile's effect.
