Rate of Reaction with Respect to Temperature

  1. Aug 11, 2014 #1
    1. The problem statement, all variables and given/known data
    The rate of a reaction at 100˚C is four times the rate at
    50˚C. What is its activation energy?
    (A) 1152 kJ. mol-1
    (B) 80.1 kJ. mol-1
    (C) 54.0 kJ. mol-1
    (D) 27.8 kJ. mol-1


    2. Relevant equations
    k=e-Ea/RT


    3. The attempt at a solution
    I plugged in the activation energies into the equation to see the changes in rate at different temperatures, but I can't solve for the one that is 4x the rate at 100 degrees.
