For the gas phase decomposition of bromoethane, CH3CH,Br—+C2H4 + HBr the rate constant has been determined at several temperatures. When In k in sis plotted against the reciprocal of the Kelvin temperature, the resulting linear plot has a slope of -2.63x10+ K and a y-intercept of 29.6. The activation energy for the gas phase decomposition of bromoethane is kJ/mol.
