  1. Question 1

    Q1. The activation energy for a reaction is 80 kJ/mol. At what temperature will the rate be double at 300 K?

    • A) 310 K
    • B) 320 K
    • C) 330 K
    • D) 340 K

    Answer: 310 K

    Explanation: Using Arrhenius equation and given that k2 = 2k1, we can find T2 = 310 K, with Ea = 80 kJ/mol and T1 = 300 K.
