1a. Hydrogen iodide decomposes when heated, forming H2 (g) and I2 (g). The rate law for this reaction is -delta[HI]/delta t = k[HI]^2. At 443 °C, k=30.L/molxmin. If the initial HI (g) concentration is 5.5x10^-2 mol/L, what concentration of HI (g) will remain after 10. minutes?

Concentration = ____ mol/L

1b. The decomposition of SO2Cl2

SO2Cl2 (g) ----> SO2 (g) + Cl2 (g)

is first-order in SO2Cl2, and the reaction has a half-life of 245 minutes at 600 K. If you begin with 3.8x10^-3 mol SO2Cl2, in 1.0-L flask, how long will it take for the amount of SO2Cl2 to decrease to 1.08x10^-4 mol?

Time = ____ min
