Objective knowledge Check Question 9 Under certain conditions the rate of this reaction is zero order in hydrogen iodide with a rate constant of 0.0057 MS": 2 HI(g) H2(g)+1(8) Suppose a 4.0 L flask is charged under these conditions with 300 mmol of hydrogen lodide. After how much time is there only 150. 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....

Calculate the lonization constant (K) for the acid. For this you will need to determine the relationship between the [HA], and the [H01. You're given [HA] and you'll need to find [H,0+- you can get this from pH. Just as we have...
