Consider the reaction

C2H6 →2CH3

at a temperature where the half-life is 15.8 minutes.

What is the first order rate constant at this temperature?

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?
