At 25°C, hydrogen iodide breaks down very slowly to hydrogen and iodine: rate = k[Hlf The rate constant at 25°C is 2.4X 10-21 L/mol-s. If 0.0100 mol of HI(g) is placed in a 1.0-L container, how long will it take for the con­centration of HI to reach 0.00900 mol/L (10.0% reacted)?

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.
