Step 1: Calculate the rate constant for the gas phase decomposition of sulfuryl chloride at 600

Question

In a study of the gas phase decomposition of nitrogen dioxide at 383 °C, the concentration of NO2 was followed as a function of time. It was found that a graph of 1/[NO2] versus time in seconds gave a straight line with a slope of 0.772 M-1 s-1 and a y-intercept of 3.88 M-1. Based on this plot, the reaction is first order in NO2 and the rate constant for the reaction is 0.772 M-1 s-1. The following data are for the gas phase decomposition of sulfuryl chloride at 600 K. SO2Cl2(g) -> SO2(g) + Cl2(g) [SO2Cl2], M 2.90×10-3 1.45×10-3 7.25×10-4 3.63×10-4 time, min 0 185 370 555 Hint: It is not necessary to graph these data. (1) The half-life observed for this reaction is 185 min. (2) Based on these data, the rate constant for this first-order reaction is 0.00376 min-1.
