The activation energy for the gas phase decomposition of bromoethane is 219 kJ. CH3 CH₂ Br →→ C₂H4+ HBr The rate constant at 719 K is 8.85 × 10-4 s¯¹. The rate constant will be 0.00974 s S .-1 at K.
For the gas phase decomposition of 2,3-dichloropropane, CH3 CHCICH₂Cl → CH3 CH=CHCl + HCl the rate constant has been determined at several temperatures. When In k in -1 S is plotted against the reciprocal of the Kelvin temperature, the resulting linear plot has a slope of -2.77 × 104 K and a y-intercept of 31.8. The activation energy for the gas phase decomposition of 2,3-dichloropropane is kJ/mol.
