The half-life for the first-order decomposition of sulfuryl chloride at 320 °C is 8.75 hours.

SOCl2 (g) → SO2 (g) + Cl2 (g)

a. What is the value of the rate constant k (in hours)?

b. What is the pressure of sulfuryl chloride 3.00 hours after the start of the reaction if its initial pressure is 722 mmHg?

c. How long after the start of the reaction will the pressure of sulfuryl chloride become 125 mmHg?
