Comparison of enzymatic and nonenzymatic rate constants

The kcat for alkaline phosphatase-catalyzed hydrolysis of methylphosphate is approximately 14/sec at pH 8 and 25°C. The rate constant for the uncatalyzed hydrolysis of methylphosphate under the same conditions is approximately 1 x 10-15/sec. What is the difference in the activation free energies of these two reactions?
