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 345 torr, what is the pressure of this substance after 74 s?
________ torr
(b) At what time will the pressure of SO2Cl2 decline to one fourth its initial value?
________ s

By what factor will the pressure of sulfuryl chloride decrease after 8 half lives? Note: The answer wants this value: (345 torr)/value = final pressure after decay

________ value
