Question

Iodine atoms will combine to form I2 in liquid hexane solvent with a rate constant of 1.5×1010L/mols. 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 2.00×102 M .

How long will it take for 89% of the newly created iodine atoms to recombine to form I2?

Express your answer using two significant figures.
