Part A lodine atoms will combine to form I2 in liquid hexane solvent with a rate constant of 1.5 x 1010L mol-1s-1. The reaction is second order in I. Since the reaction occurs so quickly, the only way to study the reaction is to create iodine atoms almost instantaneously, usually by photochemical decomposition of I2. Suppose a flash of light creates an initial I concentration of 1.50x10-2 mol L- How long will it take for 94 % of the newly created iodine atoms to recombine to form I2?
