CHM1022 Lab Report 1 Rate Law of an Iodine Clock Reaction Name: Sashini Naomi Wijesekera Student ID: 23877847 Lab Partner: Zahiya Imam Lab Session: Monday 9. 00am Aim The point of the investigation is to decide the variables that influence the pace of a response, by playing out the iodine clock response and rehashing it changing distinctive starting conditions so as to gauge and analyze the pace of response for each test and tentatively decide the rate law.
