Problem 45E

Change of Concentration with Time (Section)

As described in Exercise, the decomposition of sulfuryl chloride (SO2Cl2) is a first-order process. The rate constant for the decomposition at 660 K is 4.5 × 10-2 s-1. (a) If we begin with an initial SO2Cl2 pressure of 450 torr, what is the partial pressure of this substance after 60 s? (b) At what time will the partial pressure of SO2Cl2 decline to one-tenth its initial value? Exercise

Change of Concentration with Time (Section)

(a) The gas-phase decomposition of SO2Cl2, SO2Cl2(g)→ SO2(g) + Cl2(g), is first order in SO2Cl2. At 600 K the halflife for this process is 2.3 × 105 s. What is the rate constant at this temperature? (b) At 320 °C the rate constant is 2.2 × 10-5 s-1. What is the half-life at this temperature?
