K = _____ min-1 

How long would it take for the concentration of C2H6 to drop from 3.0 mM to 1.0 mN?

T = _____ min

If the initial concentration is 3.0 mM? what would the concentration be after 28.0 minutes?

[C2H6] = _____ mM

How long would it take to convert 95% of C2H6 at this temperature?

t = _____ min
