18. The activation energy for the reaction H2 (g) + I2 (g) 2 HI (g) → is changed from 184 kJ/mol to 59.0 kJ/mol both at 600. K by the introduction of a Pt catalyst. Calculate the ratio of the catalyzed rate constant to the un-catalyzed rate constant. Assume A is constant. Equations: = Ae–Ea/RT ln k = ln k
