For the gas phase decomposition of ethyl chloroformate, clcooC2H5-C2H5Cl + CO2 the rate constant in s-1 has been determined at several temperatures. When In k is plotted against the reciprocal of the Kelvin temperature, the resulting linear plot has a slope of -1.48x104 K and a y-intercept of 24.6. The value of the rate constant for the gas phase decomposition of ethyl chloroformate at 457 K is s1. (Enter your answer to one significant figure.)
