Decomposition of Hydroiodic Acid into Hydrogen and Iodine

Question

The decomposition of HI (Hydroiodic acid) to H2 + I2 at 508°C has a half-life of 135 min when the initial pressure of HI is 0.1 atm and 13.5 min when the pressure is 1 atm. (A) Show that this proves that the reaction is second order. (B) What is the value of the rate constant in L mol-1s-1? (C) What is the value of the rate constant in bar-1s-1? (D) What is the value of the rate constant in cm3s-1?

Summary

The question belongs to Chemical Engineering and it is about decomposition of hydroiodic acid to hydrogen and iodine at 508°C with a half time of 135 min. Questions like proving second order reaction, value of rate of constant in mole, bar and cm have been given.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
