The gas-phase decomposition of so2cl2, so2cl2(g)→so2(g)+cl2(g), is first order in so2cl2. at 600 k the half-life for this process is 2.3×105s.
part a
what is the rate constant at this temperature?
express your answer using two significant figures.
part b
at 320 ∘c the rate constant is 2.2×10−5s−1. what is the half-life at this temperature?
express your answer using two significant figures.

a. The rate constant = 0.0000030s^-1

b. The half life = 32000secs

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
