The data of the initial rate experiment of the following reaction are given below. The rate law expression of the reaction is Rate = k [ S2O8- ]x [ I- ]y. Determine the rate constant k with 3 significant figures (key-in only your value; no units are needed). Note that your k value should be reported based on the second (the time units here). Do not covert second to other time units.
