The decomposition of hydrogen iodide on finely divided gold, Ask an Expert

Academics

The decomposition of hydrogen iodide on finely divided gold 150 C is zero enter with respect to HI. The rate defined below is constant at 1.20X10-4 mol/L -s

2HI (g) -----> H2 (g) + I2 (g)
Rate = Delta (HI)/ Delta R= k = 1.20 x 10-4 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 the 0.250 M HI to decompose?
