13) The first-order decomposition of hydrogen peroxide occurs according to the equation:
2 H,O2(aq)
→ 2 H20(I) + O2(g)
If you were to use data from a concentration vs. time study of this reaction, what would you plot in order to produce
a straight line?
a) [H2O2] vs time
b) [H,O2]? vs time
1
c)
[H2O2]
vs time
d) In[H2O2] vs time
14) Dilute hydrogen peroxide in water, 3% (mass/mass), is sold over the counter to sterilize wounds. After 16 hours the
bottle has only 0.75% H2O2, given these concentrations changes and time, how many half-lives have occurred? What
is the expected half-life (t/2) for the above reaction?
15) Explain why it is not possible for the reaction below to be the elementary step for the decomposition of hydrogen
peroxide given the data presented.
2 H,02(aq) → 2 H,O(/) + O2(g)
