Sulfuryl chloride (SO2Cl2) decomposes to sulfur dioxide (SO2) and chlorine (Cl2) in the gas phase. The following data were obtained when a sample containing 5.00x10-2 moles of sulfuryl chloride was heated to 600 K in a 5.00x10-1 L container. Define the rate of reaction as
-d[SO2Cl2]/dt. Use the data in the table below to answer the following questions.
a. Determime the value of the rate constant k for the decomposition reaction at 600 K.
b. What is the half-life of the reaction/
c. What would be the pressure in the vessel after 0.500 hours and after 12.0 hours?
d. What fraction of the sulfuryl chloride remains after 20.0 hours?
