Under certain conditions the rate of this reaction is zero order in hydrogen iodide with a rate constant of 0.0027 M·s ': 2 HI (g) – H2 (g) +I, (g) Suppose a 250. mL flask is charged under these conditions with 500. mmol of hydrogen iodide. After how much time is there only 250. mmol left? You may assume no other reaction is important. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
