Rate constant and temperature

  1. Dec 12, 2009 #1
    1. The problem statement, all variables and given/known data
    How is the rate constant related to temperature when other variables are constant

    2. Relevant equations
    Arrhenius equation: k=Ae^Ea/RT

    3. The attempt at a solution
    I know it is just a matter of rearranging but I can't seem make it end up as k ∝ T in some way.
    I tried using logarithms and ln(k2/k1) = -Ea/RT(1/T2 - 1/T1) and cant get it
    I think this is the same question as https://www.physicsforums.com/showthread.php?t=203424 and it was tagged as solved but it was not.

    No idea what you are asking about - Arrhenius equation gives you dependence between rate constant and temperature, isn't it exact answer to your question?
