HO 2 is a highly reactive chemical species that plays a role in atmospheric chemistry. The rate of the gas-phase reaction 2HO 2(g) → H 2O 2(g) + O 2(g) is second order in [HO 2] , with a rate constant at 25°C of 1.4*109 M− 1 s− 1 . Suppose some HO 2 with an initial concentration of 2.0*10− 8 M could be confined at 25°C. Calculate the concentration that would remain after 1 s, assuming no other reactions take place.

Chlorine monoxide accumulates in the stratosphere above
Antarctica each winter and plays a key role in the formation of the
ozone hole above the South Pole each spring. Eventually, ClO
decomposes according to the equation:
$$2ClO(g)Cl2(g)+O2(g)
The second-order rate constant for the decomposition of ClO is
6.58×109 M–1s–1 at a particular
