Question

Three experiments were conducted at 25?C to
discover how the initial rate of degradation of
ozone in the presence of NO (g) varies as the
concentration of the reactants change.
NO(g) + O3(g) -> NO2(g) + O2(g)

       Initial        Initial         Initial Rate
Exp [NO]           O3       ofReaction
(×104 M)  (×105 M)    (M· s1)
1         18.0          15.0        2.16 ×105
2         9.00          7.50        5.40 ×106
