Under certain conditions the rate of this reaction is zero order in hydrogen iodide with a rate constant of 0.0099 Mºs!! 2 HI(g) + H2(g)+12(8)
Suppose a 500 ml flask is charged under these conditions with 350 mmol of hydrogen iodide. How much is left 20. s later? 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.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
