  1. Question 1

    Q1. The rate constant for a reaction is 0.05 s-1 at 300 K. If the activation energy is 100 kJ/mol, what is the rate constant at 320 K?

    • A) 0.15 s-1
    • B) 0.2 s-1
    • C) 0.1 s-1
    • D) 0.25 s-1

    Answer: 0.15 s-1

    Explanation: Using the Arrhenius equation, we can calculate k2 = 0.15 s-1.
