Use the References to access important values if needed for this question. The gas phase decomposition of hydrogen iodide at 700 K HI(g)-----> ½ H2(g) + ½ I2(g) is second order in HI. In one experiment, when the initial concentration of HI was 1.57 M, the concentration of HIdropped to 0.237 M after 1.93×103 seconds had passed. Based on these data, the rate constant for the reaction is_____ M-1 s-1.
