The reaction rate triples when the temperature increases from 15 to 35 degree C. What is the activation energy?

  • Chemistry -

    I believe you use the Arrhenius equation. Make the k values a ratio of 3.

  • Chemistry -

    From Arhenius Equation
    ln(k1/k2)= Ea/R((T1-T2)/(T1T2))
    The ratio of rate constant is 1:3;
    R= 8.314JK.mole
    T1=288K
    T2=308K
    So;
    ln(1/3)=Ea/8.314((288-308)/(288x308))
    Ea=4.05x10⁴J or 4.05x10¹Kj
