The activation energy for the gas phase decomposition of difluoroperoxide is 72.4 kJ. F2O2F2 + O2 The rate constant at 222.0 K is 0.0000570 /s. The rate constant will be ____ /s at 269.0 K.
3. For the gas phase decomposition of difluoroperoxide, F2O2F2 + O2, the rate constant in s-1 has been determined at several temperatures. When ln k is plotted against the reciprocal of the Kelvin temperature, the resulting linear plot has a slope of -8.71×10^3 K and a y-intercept of 29.4. The value of the rate constant for the gas phase decomposition of difluoroperoxide at 237 K is ____ s-1. (Enter your answer to one significant figure.)
