Molecular iodine, I2(g), dissociates into iodine atoms at 625 K with a first-order rate constant of 0.271 s−1 . If you start with 0.040 M of I2 at this temperature, how much will remain after 7.68 s assuming that the iodine atoms do not recombine to form I2?
Express the molarity to two significant figures.
