Chemists commonly use a rule of thumb that an increase of 10 K in temperature doubles the rate of a reaction. What must the activation energy be for this statement to be true for a temperature increase from 49 to 59°C?© BrainMass Inc. brainmass.com December 24, 2021, 4:59 pm ad1c9bdddf
49 deg = 49 + 273 = 322 K
59 deg = 59 + 273 = 332 K
We have the Arrhenius equation: k = A exp[-Ea/RT]
ln k = ln A - Ea/(RT)
Let k1 and k2 ...
The solution includes a calculation of activation energy using the Arrhenius equation, given the change in temperature of a solution.
