Question about activation energy
« on: December 06, 2005, 05:27:17 PM »
I know that when you increase a reaction at room temperature (25 degrees) by 10 degrees it doubles the reaction rate, but what activation energy is implied by this?

K = Ae-Ea/RT
ln K = ln A - Ea/RT
Ea/RT = ln A - ln K = ln (A/K)
RT = Ea/ln(A/K)
Ea = RT.ln(A/K)
