### Re: Arrhenius Equation, Temperature, and Rate Constants

Arrhenius equation: k=Ae^(-Ea/RT)

From it, you get the equation: ln(k2/k1)=(-Ea/R)(1/T2-1/T1)

If the problem asks you to solve k or Ea at one T, use the first equation. If the tells you to find k for a certain reaction at different reaction, use the second equation.
