Solved: The decomposition of hydrogen iodide on finely
Chapter 15, Problem 15.52(choose chapter or problem)
The decomposition of hydrogen iodide on finely divided gold at 1508C is zero order with respect to HI. The rate defined below is constant at 1.20 3 1024 mol/L ? s. 2HI(g) 88n H2(g) 1 I2(g) Rate 5 2d 3HI4 dt 5 k 5 1.20 3 1024 mol/L ? s a. If the initial HI concentration was 0.250 mol/L, calculate the concentration of HI at 25 minutes after the start of the reaction. b. How long will it take for all of the 0.250 M HI to decompose?
