The decomposition of hydrogen peroxide is first order in H2O2:
2H2O2(aq) → 2H2O(l) + O2(g) Rate = k [H2O2]
How long will it take for half of the H2O2 in a 10-gal sample to be consumed if the rate constant for this reaction is 5.6 x 10-2 s-1?

    ln(No/N) = akt
    ln(10/5) = 2*0.056t
    Solve for t.
